Plain language summary
Efforts to improve pregnancy rates remain largely focused on enhancing the quality of the transferred embryo. However, there is increasing awareness of the potential role of the intra-uterine environment as a determinant for success. The aim of this study was to determine if lactobacilli-loaded vaginal capsules are superior to placebo in improving a vaginal microbiota reported as unfavourable to implantation in women scheduled for fertility treatment. This study is a single-centre, two-arm, double-blinded, randomised controlled study. The study enrolled women aged 18–40 years who were referred to the Fertility Clinic and whose vaginal microbiota prior to fertility treatment had been diagnosed as an unfavourable. Participants (n=77) were randomised in a 1:1 ratio to either lactobacilli-loaded vaginal capsules or placebo. Results did not show any significant effect of treatment with lactobacilli-loaded vaginal capsules on the unfavourable vaginal microbiota profile among women referred to fertility treatment. However, the study showed the highly dynamic nature of the vaginal microbiota, with a spontaneous improvement rate of 34.2% (of the patients) one to three months after the baseline sample. Authors conclude that probiotics use for the improvement of vaginal microbiota should be tempered with some caution. More studies of both the vaginal and endometrial microbiota are required to confirm the efficacy of specific vaginal probiotics before they can be considered as a therapeutic solution.
Abstract
OBJECTIVE To investigate whether treatment with proprietary lactobacilli-loaded vaginal capsules improves an unfavorable vaginal microbiome diagnosed using a commercially available test and algorithm. DESIGN A randomized, double-blinded, placebo-controlled study was conducted in 74 women prior to undergoing fertility treatment at a single university fertility clinic between April 2019 and February 2021. The women were randomly assigned in a 1:1 ratio to receive one vaginal capsule per day for 10 days containing either a culture of more than 108 CFU of Lactobacillus gasseri and more than 108 CFU Lactobacillus rhamnosus (lactobacilli group) or no active ingredient (placebo group). Vaginal swabs for microbiota analysis were taken at enrollment, after treatment and in the cycle following treatment. PARTICIPANTS AND METHODS Women aged 18-40 years who prior to fertility treatment were diagnosed with an unfavorable vaginal microbiota, characterized by either a low relative load of Lactobacillus or a high proportion of disrupting bacteria using the criteria of the IS-pro™ diagnostic system (ARTPred, Amsterdam, the Netherlands), were enrolled in the study. The primary outcome measure was the proportion of women with improvement of the vaginal microbiota after intervention. RESULTS The vaginal microbiota improved after intervention in 34.2% of all participants (lactobacilli group 28.9%, placebo group 40.0%), with no significant difference in the improvement rate between the lactobacilli and placebo groups, RR = 0.72 (95% CI 0.38-1.38). CONCLUSION This study indicates that administering vaginal probiotics may not be an effective means of modulating the vaginal microbiome for clinical purposes in an infertile population. However, a spontaneous improvement rate of 34.2% over a period of one to three months, confirming the dynamic nature of the vaginal microbiota, indicates that a strategy of postponing further IVF treatment to await microbiota improvement may be relevant in some patients, but further research is needed.

Plain language summary
Early-life microbiome acquisition and development can be compromised by external perturbations such as delivery via caesarean section (CS), formula feeding and antibiotics. Currently, based on revised international guidelines, all infants born by CS are exposed to broad-spectrum antibiotics via the umbilical cord. Even though there was not an increase in the incidence of neonatal sepsis, the effects on the gut microbiota colonisation and long-term health consequences remain largely unknown. The hypothesis for this study was that exposure to antibiotics in children delivered by CS, related to the revised international guidelines, influences the microbial colonisation process and may impact health outcome. This study is a randomised controlled trial on the microbiome and health state of infants up to 3 years of age. The study enrolled women delivering via CS who received antibiotics prior to skin incision (n=20) or after umbilical cord clamping (n=20) and women who had a vaginal delivery (n=23). Results show that CS delivery in general leads to a profound impact on the initial microbial colonisation. Furthermore, maternal antibiotic administration prior to CS does not lead to a ‘second hit’ on the already compromised microbiome in CS born infants. Authors conclude that early-life microbiome development is strongly affected by mode of delivery.
Abstract
OBJECTIVE Revised guidelines for caesarean section (CS) advise maternal antibiotic administration prior to skin incision instead of after umbilical cord clamping, unintentionally exposing the infant to antibiotics antenatally. We aimed to investigate if timing of intrapartum antibiotics contributes to the impairment of microbiota colonisation in CS born infants. DESIGN In this randomised controlled trial, women delivering via CS received antibiotics prior to skin incision (n=20) or after umbilical cord clamping (n=20). A third control group of vaginally delivering women (n=23) was included. Faecal microbiota was determined from all infants at 1, 7 and 28 days after birth and at 3 years by 16S rRNA gene sequencing and whole-metagenome shotgun sequencing. RESULTS Compared with vaginally born infants, profound differences were found in microbial diversity and composition in both CS groups in the first month of life. A decreased abundance in species belonging to the genera Bacteroides and Bifidobacterium was found with a concurrent increase in members belonging to the phylum Proteobacteria. These differences could not be observed at 3 years of age. No statistically significant differences were observed in taxonomic and functional composition of the microbiome between both CS groups at any of the time points. CONCLUSION We confirmed that microbiome colonisation is strongly affected by CS delivery. Our findings suggest that maternal antibiotic administration prior to CS does not result in a second hit on the compromised microbiome. Future, larger studies should confirm that antenatal antibiotic exposure in CS born infants does not aggravate colonisation impairment and impact long-term health.

Plain language summary
Arthritic disease is a chronic inflammatory condition affecting one or more joints. Over 100 different forms of arthritis have been identified. Despite their different causes (i.e. degenerative, autoimmune), they share common symptoms such as joint pain, swelling, stiffness, and reduced mobility, which can be disabling in many cases. Drug treatment focuses mainly on limiting the progression of the disease, reducing joint inflammation and managing pain. However, these drugs are associated with many side effects. The rhizome of Curcuma longa (CL), also known as turmeric, has longstanding use as an anti-inflammatory in traditional Asian medicines. Research has affirmed its anti-inflammatory and immunosuppressive properties. Evidence from multiple clinical trials suggests that curcumin, one of the active compounds of CL, can reduce the subjective experience of pain in some conditions and can also improve the symptoms and inflammation associated with arthritis. Hence this systematic review sought to evaluate the efficacy and safety of CL-extract in 5 types of arthritis (including Ankylosing Spondylitis, Rheumatoid Arthritis, Osteoarthritis, Juvenile idiopathic arthritis and gout). The review included 29 randomized controlled trials involving 2396 participants, with dosages ranging from 120 mg to 1500 mg for a period of 4-36 weeks. Overall, curcumin and CL extract appeared to improve inflammation and pain levels in arthritic subjects whilst demonstrating safety with no increases in adverse effects. CL and its active constituents appeared to favourably change immune and inflammatory responses, as well as serum uric acid levels in the reviewed forms of arthritis. However, due to the small sample numbers in the trials and some lower quality studies, the authors advocate to interpret the results with caution until more solid evidence is available.
Abstract
Background: Modern pharmacological research found that the chemical components of Curcuma longa L. are mainly curcumin and turmeric volatile oil. Several recent randomized controlled trials (RCT) have shown that curcumin improves symptoms and inflammation in patients with arthritis. Methods: Pubmed, Cochran Library, CNKI, and other databases were searched to collect the randomized controlled trials (RCTs). Then, the risk of bias of RCTs were assessed and data of RCTs were extracted. Finally, RevMan 5.3 was utilized for meta-analysis. Results: Twenty-nine (29) RCTs involving 2396 participants and 5 types of arthritis were included. The arthritis included Ankylosing Spondylitis (AS), Rheumatoid Arthritis (RA), Osteoarthritis (OA), Juvenile idiopathic arthritis (JIA) and gout/hyperuricemia. Curcumin and Curcuma longa Extract were administered in doses ranging from 120 mg to 1500 mg for a duration of 4-36 weeks. In general, Curcumin and Curcuma longa Extract showed safety in all studies and improved the severity of inflammation and pain levels in these arthritis patients. However, more RCTs are needed in the future to elucidate the effect of Curcumin and Curcuma longa Extract supplementation in patients with arthritis, including RA, OA, AS and JIA. Conclusion: Curcumin and Curcuma longa Extract may improve symptoms and inflammation levels in people with arthritis. However, due to the low quality and small quantity of RCTs, the conclusions need to be interpreted carefully.

Plain language summary
Cervical cancer remains the fourth most prevalent cancer in women worldwide. The infection of certain strains of human papillomavirus (HPV)) are thought to have an important causative role in the development of cervical cancer. But since a vast majority of HPV infections clear naturally within a few months, this indicates other factors at play determine the progression of the disease and its cancerous developments. Recent findings indicate that there may be a close link between disruptions of the vaginal microbiome and HPV infection, cervical lesions, cervical cancer and other gynaecological diseases. However, the evidence thus far is quite varied. Hence this systematic review sought to gather the current evidence and integrate it to create up-to-date knowledge. Included were the 22 studies relating to vaginal microbiota, and women with HPV-associated cervical diseases. The studies were conducted in various countries around the world and contained a mixture of case-controlled, cross-sectional and longitudinal studies. The authors acknowledge the challenges of summarising the findings due to differences in how the studies have been conducted. The results of the review showed that vaginal disturbances in HPV infections and related cervical diseases, seem to manifest in decreases in Lactobacilli, and increases in aerobic and anaerobic bacteria. Lactobacillus iners seemed to have either protective or pathogenic effects. They also noted that there are geographical and ethnic differences and patterns, which made the consolidation of results more challenging. For future research, the authors deemed the role of the Lactobacillus family of particular interest.
Abstract
BACKGROUND Emerging evidence has demonstrated a close association between perturbations in vaginal microbiota composition in women and human papillomavirus (HPV) infection, cervical lesions, and cervical cancer (Ca); however, these findings are highly heterogeneous and inconclusive. AIM: To perform a comprehensive systematic review of the global disturbance in the vaginal microbiota, specifically in women with HPV-associated cervical diseases, and to further conduct within- and across-disease comparisons. METHOD Twenty-two records were identified in a systematic literature search of PubMed, Web of Science, and Embase up to February 28, 2022. We extracted microbial changes at the community (alpha and beta diversity) and taxonomic (relative abundance) levels. Within- and across-disease findings on the relative abundance of taxonomic assignments were qualitatively synthesized. RESULTS Generally, significantly higher alpha diversity was observed for HPV infection, cervical lesions, and/or cancer patients than in controls, and significant differences within beta diversity were observed for the overall microbial composition across samples. In within-disease comparisons, the genera Gardnerella, Megasphaera, Prevotella, Peptostreptococcus, and Streptococcus showed the greatest abundances with HPV infection; Sneathia and Atopobium showed inconsistent abundance with HPV infection, and Staphylococcus was observed in Ca. Across diseases, we find increased levels of Streptococcus and varying levels of Gardnerella were shared across HPV infections, high-grade squamous intraepithelial lesions, and Ca, whereas Lactobacillus iners varied depending on the HPV-related disease subtype. CONCLUSIONS This systematic review reports that vaginal microbiome disturbances are correlated to the depletion of Lactobacillus, enrichment of anaerobes, and increased abundance of aerobic bacteria in HPV infection and related cervical diseases. Moreover, L. iners may exert either protective or pathogenic effects on different HPV-related diseases.

Plain language summary
The long-term effects of COVID-19 is becoming increasingly documented in adults. Symptoms such as fatigue, headache and depression have all been reported, however data on the possible long-term effects of COVID-19 in children is scarce. The aim of this systematic review and case report was to describe the long-term effects of COVID-19 in five children and support this with other reports in the literature. The results showed that of the five case reports of long COVID, four were girls aged 9-15 years. All subjects reported symptoms lasting between 6-8 months. Most common symptoms were fatigue, difficulty breathing and heart issues. The systematic literature review did not find any publications which documented long COVID in children. It was concluded that children may experience long COVID symptoms and girls may be more susceptible. This study could be used by healthcare professionals to understand that children may also be affected by long COVID and that patients should be monitored for symptoms for at least 6-8 months.
Abstract
AIM: Persistent symptoms in adults after COVID-19 are emerging and the term long COVID is increasingly appearing in the literature. However, paediatric data are scarce. METHODS This paper contains a case report of five Swedish children and the long-term symptoms reported by their parents. It also includes a systematic literature review of the MEDLINE, EMBASE and Web of Science databases and the medRxiv/bioRxiv pre-print servers up to 2 November 2020. RESULTS The five children with potential long COVID had a median age of 12 years (range 9-15) and four were girls. They had symptoms for 6-8 months after their clinical diagnoses of COVID-19. None were hospitalised at diagnosis, but one was later admitted for peri-myocarditis. All five children had fatigue, dyspnoea, heart palpitations or chest pain, and four had headaches, difficulties concentrating, muscle weakness, dizziness and sore throats. Some had improved after 6-8 months, but they all suffered from fatigue and none had fully returned to school. The systematic review identified 179 publications and 19 of these were deemed relevant and read in detail. None contained any information on long COVID in children. CONCLUSION Children may experience similar long COVID symptoms to adults and females may be more affected.

Plain language summary
Chlamydia trachomatis (CT) is the agent of the most common bacterial sexually transmitted infection (STI) worldwide. This study is a cohort study. The composition of vaginal and anal microbiome in a cohort of sexually active young women was investigated comparing the bacterial composition of CT-infected women (n = 10) to a negative control group (n = 16). Results showed that: - both vaginal and anal ecosystems were characterised by a degree of dysbiosis in case of CT infection, with several changes in the microbial composition compared to CT-negative women. - bacteria dominance was different for patients with anal CT infection (Parvimonas and Pseudomonas), than those of CT-negative women (Escherichia and Enterococcus). - there were significant differences in several functional pathways between CT-positive patients and the control group. Among all, a higher involvement of chorismate and aromatic amino acid biosynthesis, as well as an increase in mixed acid fermentation, were predicted at the vaginal level of CT-positive patients. Authors conclude that their findings could be useful to set up new diagnostic/prognostic tools, to find correlations with the presence of peculiar clinical or behavioural traits, and to evaluate the possibility of a different susceptibility to chlamydial STIs based on microbiome composition.
Abstract
Background.Chlamydia trachomatis (CT) is the agent of the most common bacterial sexually transmitted infection worldwide, with a significant impact on women's health. Despite the increasing number of studies about the vaginal microbiome in women with CT infections, information about the composition of the anal microbiome is still lacking. Here, we assessed the bacterial community profiles of vaginal and anal ecosystems associated or not with CT infection in a cohort of Caucasian young women. Methods. A total of 26 women, including 10 with a contemporary vaginal and ano-rectal CT infection, were enrolled. Composition of vaginal and anal microbiome was studied by 16S rRNA gene profiling. Co-occurrence networks of bacterial communities and metagenome metabolic functions were determined. Results. In case of CT infection, both vaginal and anal environments were characterized by a degree of dysbiosis. Indeed, the vaginal microbiome of CT-positive women were depleted in lactobacilli, with a significant increase in dysbiosis-associated bacteria (e.g., Sneathia, Parvimonas, Megasphaera), whereas the anal microbiota of CT-infected women was characterized by higher levels of Parvimonas and Pseudomonas and lower levels of Escherichia. Interestingly, the microbiome of anus and vagina had numerous bacterial taxa in common, reflecting a significant microbial 'sharing' between the two sites. In the vaginal environment, CT positively correlated with Ezakiella spp. while Gardnerella vaginalis co-occurred with several dysbiosis-related microbes, regardless of CT vaginal infection. The vaginal microbiome of CT-positive females exhibited a higher involvement of chorismate and aromatic amino acid biosynthesis, as well as an increase in mixed acid fermentation. Conclusions. These data could be useful to set up new diagnostic/prognostic tools, offering new perspectives for the control of chlamydial infections.

Little research has been conducted about menopause in First Nations women. In response to the wishes of Cree women living in Maskwacis, Alberta, a community-based participatory research (CBPR) project was conducted to explore menopause experience and raise awareness of menopause symptoms in the community. Local women between the ages of 40–65 years were invited to participate in workshops, they also completed questionnaires. The five workshops included a total of 37, mostly post-menopausal women. The main discussion themes were: ‘experiences of menopause symptoms’ including their impact on quality of life; ‘menopause knowledge prior to their own experience’ with most women feeling that they had insufficient information before menopause; ‘menopause symptom management’ which mainly included practical strategies; ‘impact of menopause on family members’ which was of prime concern with uncontrollable mood changes affecting the whole family and sometimes causing matrimonial disharmony. These workshops identified a need for increasing menopause awareness, particularly for partners and other family members.
Abstract
BACKGROUND Little research has been conducted about menopause in First Nations women. In response to the wishes of Cree women living in Maskwacis, Alberta, to start a dialogue on menopause, we undertook community-based participatory research (CBPR) to explore menopause experience and raise awareness of menopause symptoms in the community. METHODS The research adhered to the principles of Ownership, Control, Access and Possession (OCAP™) and was guided by the interest of the participating women. Local women (target age 40-65 years) were invited to participate in workshops using word-of-mouth and community posters in health centers. Five research workshops were held in community settings, attended by experienced women's health researchers and consenting women. The participants guided the informal discussions. They also completed questionnaires which included menopause-related quality of life. The researchers used extensive hand-written field notes to record data; qualitative content analysis was applied to identify themes. Simple descriptive analysis was used for the questionnaire results. The findings were discussed at a community feedback session and laid the basis for further knowledge translation initiatives. RESULTS The five workshops included a total of 37, mostly post-menopausal women with 6-11 women/workshop. The main discussion themes were: "experiences of menopause symptoms" including their impact on quality of life; "menopause knowledge prior to their own experience" with most women feeling that they had insufficient information before menopause; "menopause symptom management" which mainly included practical strategies; "impact of menopause on family members" which was of prime concern with uncontrollable mood changes affecting the whole family and sometimes causing matrimonial disharmony. Questionnaire responses corroborated the workshop discussions. Knowledge translation of the research findings produced two information pamphlets specifically for the Maskwacis community: one for husband/partner, the other for women and family members. These pamphlets have been distributed in all areas of the community. CONCLUSION This CBPR project addressed a topic identified by the community as being important. Community members developed informative pamphlets in response to the women's concern of lack of understanding for menopause symptoms among families. This simple solution has been widely accepted by community members, opening the possibility of wider discussion about menopause.

Plain language summary
A long-term use of cardiovascular medications significantly reduces the risk of morbidity and mortality, but their full therapeutic potential cannot be achieved if patients are nonadherent. Developing interventions to tackle medication nonadherence is important for improving health outcomes. The aim of this study was to evaluate the effectiveness of app-based interventions on medication adherence in patients with cardiovascular disease (CVD). This study is a systemic review and meta-analysis of 16 randomised controlled trials. The apps used were all different for each study and were developed by different organizations: 8 were academic or government institutions, whereas others were commercial organizations. Results show that a total of 9 trials showed a statistically significant improvement in medication adherence in the intervention arm. Furthermore, the apps used had mixed functionality, including reminders, education or both, however, overall, user engagement and usability were rated positively, demonstrating interest in the concept. Authors conclude that it is difficult to make strong, unrestricted recommendations for practice, especially with the methodological limitations of the trials included in this study. However, mobile apps may enhance medication adherence as part of a package of care.
Abstract
BACKGROUND Adherence rates of preventative medication for cardiovascular disease (CVD) have been reported as 57%, and approximately 9% of all CVD events in Europe are attributable to poor medication adherence. Mobile health technologies, particularly mobile apps, have the potential to improve medication adherence and clinical outcomes. OBJECTIVE The objective of this study is to assess the effects of mobile health care apps on medication adherence and health-related outcomes in patients with CVD. This study also evaluates apps' functionality and usability and the involvement of health care professionals in their use. METHODS Electronic databases (MEDLINE [Ovid], PubMed Central, Cochrane Library, CINAHL Plus, PsycINFO [Ovid], Embase [Ovid], and Google Scholar) were searched for randomized controlled trials (RCTs) to investigate app-based interventions aimed at improving medication adherence in patients with CVD. RCTs published in English from inception to January 2020 were reviewed. The Cochrane risk of bias tool was used to assess the included studies. Meta-analysis was performed for clinical outcomes and medication adherence, with meta-regression analysis used to evaluate the impact of app intervention duration on medication adherence. RESULTS This study included 16 RCTs published within the last 6 years. In total, 12 RCTs reported medication adherence as the primary outcome, which is the most commonly self-reported adherence. The duration of the interventions ranged from 1 to 12 months, and sample sizes ranged from 24 to 412. Medication adherence rates showed statistically significant improvements in 9 RCTs when compared with the control, and meta-analysis of the 6 RCTs reporting continuous data showed a significant overall effect in favor of the app intervention (mean difference 0.90, 95% CI 0.03-1.78) with a high statistical heterogeneity (I2=93.32%). Moreover, 9 RCTs assessed clinical outcomes and reported an improvement in systolic blood pressure, diastolic blood pressure, total cholesterol, and low-density lipoprotein cholesterol levels in the intervention arm. Meta-analysis of these clinical outcomes from 6 RCTs favored app interventions, but none were significant. In the 7 trials evaluating app usability, all were found to be acceptable. There was a great variation in the app characteristics. A total of 10 RCTs involved health care professionals, mainly physicians and nurses, in the app-based interventions. The apps had mixed functionality: 2 used education, 7 delivered reminders, and 7 provided reminders in combination with educational support. CONCLUSIONS Apps tended to increase medication adherence, but interventions varied widely in design, content, and delivery. Apps have an acceptable degree of usability; yet the app characteristics conferring usability and effectiveness are ill-defined. Future large-scale studies should focus on identifying the essential active components of successful apps.

Psoriasis is a common inflammatory skin disease that results in patches of dry, scaly skin that can be itchy or sore. Psoriatic arthritis is an inflammatory arthritis that affects up to 30% of psoriasis patients. There is growing interest in the association between the microbiome and inflammatory conditions. This systematic review examined the role of the oral and gut microbiota and the effect of probiotics in patients with psoriasis and/or psoriatic arthritis. 23 studies were included in the analysis. Studies examined the microbiota using culture or 16S ribosomal RNA gene sequencing analysis. The results showed an increased presence of Candida in the mouth, and an altered gut microbiota in patients with psoriatic disease compared with healthy controls. Probiotics were associated with a significant decrease in psoriasis severity, but the microbiota was unchanged. The study authors concluded that further research is required into the role of the microbiome in patients with psoriasis.
Abstract
Advances in technology have led to an increased number of studies investigating the microbiome in patients with psoriasis. This systematic review examined data regarding the oral and gut microbiota in patients with psoriasis and/or psoriatic arthritis and the effect of probiotics on the microbiota and severity of psoriasis. Of 1,643 studies, 23 were included (22 observational, 1 interventional). Studies examined the microbiota using culture or 16S rRNA gene sequencing analysis. All culture-based studies identified an increased presence of oral Candida in patients with psoriasis, whereas small variations in the oral microbiota were found in a 16S rRNA gene-based study. All 16S rRNA gene sequencing based studies agreed that the gut microbiota of patients with psoriatic disease differed from that of healthy controls, but the results were heterogeneous. Probiotics were associated with a significant improvement in the severity of psoriasis, but did not change microbiota. Overall, studies lacked relevant inclusion criteria and baseline information. In conclusion, the role of the microbiota in patients with psoriasis requires further investigation using more robust methods.

Plain language summary
Nutritional needs vary depending on the stage in a woman’s lifecycle. Women of child-bearing age (WCBA) and women of menopausal age (WMENO) are at high risk of not meeting required nutrient amounts, yet data is limited on nutrient intakes in these groups. This observational study of 4134 WCBA and 3438 WMENO aimed to determine any nutrient gaps and if associations exist between dietary intake and blood levels of key nutrients. The results showed that WCBA and WMENO had inadequate dietary intakes of calcium, magnesium, and vitamins A, C, D and E, which was allevaited by supplementation. Women who had lower levels of folate, vitamins D, B12 and essential fatty acids had lower dietary intakes of these nutrients, indicating a risk of deficiency. It was concluded that many women of WCBA and WMENO may have inadequate dietary nutrient intake and supplementation may improve this. This study could be used by healthcare professionals to understand that nutrient intakes may be inadequate in WCBA and WMENO. Dietary recommendations to increase nutrient intake would be advisable, however if individuals are still not meeting nutrient requirements, nutrient supplementation may be advisable.
Abstract
BACKGROUND Women of childbearing age (WCBA) and women of menopausal age (WMENO) have distinct nutritional needs. Understanding nutrient intake and status in these life stages is critical for tailoring dietary recommendations. OBJECTIVES The objectives of this study were to evaluate total estimated usual nutrient intakes from food and food plus supplements and to compare these to established recommendations for WCBA and WMENO life stages and examine associations between self-reported estimated usual intakes and nutrient status biomarkers. METHODS Twenty-four-hour dietary recall data from 2011-2016 NHANES were used to estimate usual intake of nutrients from food and food plus supplements for WCBA (aged 15-44 y, n = 4,134) and WMENO (aged 40-65 y, n = 3,438). Estimates of mean usual intake were derived and compared across clinically defined nutrient biomarker categories. RESULTS Both young (aged 15-30 y) and older (aged 31-44 y) WCBA had intakes from food below the Estimated Average Requirement (EAR) for calcium (49% and 44%, respectively), magnesium (62%, 44%), and vitamins A (50%, 44%), C (47%, 46%), D (>97%, >97%), and E (92%, 88%). Similarly, perimenopausal (aged 40-50 y) and menopausal (aged 51-65 y) women had intakes from food below the EAR for calcium (48% and 74%, respectively), magnesium (50%, 49%), and vitamins A (44%, 37%), C (44%, 41%), D (>97%, >97%), and E (88%, 86%). Nutrient gaps decreased with supplement usage. For folate, vitamins D and B-12, and DHA, women in the lowest biomarker category (indicating increased risk of deficiency) had significantly lower intake from food (315.2 ± 25.9 compared with 463.8 ± 5.2 µg dietary folate equivalents, 3.5 ± 0.1 compared with 4.2 ± 0.1 µg, 3.6 ± 0.2 compared with 4.3 ± 0.1 µg, and 0.037 ± 0.005 compared with 0.070 ± 0.006 g, respectively; P < 0.01) of the corresponding nutrient compared with the highest biomarker category. CONCLUSIONS Substantial percentages of WCBA and WMENO are not meeting recommendations for multiple nutrients, whereas supplement usage partially fills nutrient gaps. Dietary intake was positively associated with most nutrient status biomarkers. Specific guidance is needed to ensure adequate nutrient intakes and nutrient status during these critical life stages.
