Nutrients. 2023;(7)
Abstract
Osteosarcopenic adiposity (OSA) syndrome denotes the confluence of bone, muscle, and adipose tissue deterioration. Being a complex entity, numerous uncertainties about OSA still exist, despite the extensive research on the topic. Our objectives were to evaluate human studies addressing dietary intake/nutritional status and the quantity/types of physical activity related to OSA. The search in PubMed, Scopus, and Web of Science databases was conducted to examine relevant articles published from inception to the end of December 2022, utilizing the MeSH strings in the search strategy. Only studies published in English and conducted in humans (≥18 years) without chronic conditions (cancers, kidney/liver disease) or pregnancy were used. Book chapters, abstracts-only, and studies in which participants did not have all three body composition components measured to identify OSA or when body composition components could not be related to the independent/exposure variables were excluded. A total of n = 1020 articles were retrieved from all three databases and eight more from the reference lists. After the exclusion of duplicates and other unsuitable articles, n = 23 studies were evaluated. Among those, eleven were from epidemiological or cross-sectional studies relating nutrients/dietary intake or nutritional status with OSA. Another four examined the relationship between serum biomarkers (vitamin D and ferritin) with OSA, while eight articles presented the results of the interventional studies with resistance training. Overall, higher protein, calcium, potassium, and vitamins D and C intakes emerged as nutrients positively modifying OSA, along with a diet higher in fruits and low-fat dairy foods. Higher serum vitamin D and ferritin were respectively positively and negatively related to OSA. Resistance training was a safe intervention yielding several beneficial outcomes for the OSA syndrome in older women.

Ilich, JZ, Liu, PY, Shin, H, Kim, Y, Chi, Y
Nutrients. 2022;(5)
Abstract
The role of dairy foods and calcium/vitamin D supplements in cardiometabolic diseases is unknown. The objective of this secondary analysis is to investigate cardiometabolic risk factors changes after a 6-month weight-loss intervention in overweight/obese postmenopausal women divided in three groups: Ca+vitamin D supplements (S); low-fat dairy foods (D; 4−5 servings/day); or control/placebo pills (C), as complements to hypocaloric diets. The original study focused on bone/body composition. This analysis included blood pressure (BP), and serum triglycerides, lipids (including apoproteins Apo1 and ApoB), adipokines, and C-reactive protein in n = 97 participants who finished with complete data points. Systolic BP decreased 5.1%, 4.8%, and 1.8% in S, D, and C groups, respectively (p < 0.05 for S and D vs. baseline and vs. C at 6 months). Reduction in triglycerides and ratio of total cholesterol (TC)/high-density lipoproteins cholesterol (HDL-C) was the highest in S, while the reduction in TC and LDL-C was the highest in D group (all p < 0.05). Leptin and ApoB significantly decreased and adiponectin and ApoA1 increased in all groups. In conclusion, although the C group’s participants experienced an improvement in some of the cardiometabolic indices with weight loss, those in the S and D groups showed significantly better results in most of the outcomes, indicating the beneficial effects of low-fat dairy foods and/or Ca+vitamin D intake as complements to a hypocaloric diet.

Osteosarcopenic adiposity syndrome update and the role of associated minerals and vitamins.
Ilich, JZ
The Proceedings of the Nutrition Society. 2021;(3):344-355
Abstract
The objectives are to present an updated synopsis on osteosarcopenic adiposity (OSA) syndrome and evaluate the roles of selected micronutrients in its prevention and management. OSA refers to the concurrent deterioration of bone (osteopenia/osteoporosis), muscle (sarcopenia) and adipose tissue expansion. It portrays the most advanced stage in a continuum of body composition disorders. Although OSA has been widely studied involving the populations of different backgrounds, its prevalence is hard to collate because different methodologies and criteria were used for its diagnosis. Another critical health aspect is the presence of low-grade chronic inflammation (LGCI) which contributes to OSA and vice versa. Nutrition is important in the prevention and management of both OSA and LGCI. Although micronutrients act in numerous metabolic and physiological processes, their roles here are presented in relation to OSA (and its components) and LGCI in general and relevant to the COVID-19 pandemic. These include calcium, magnesium, phosphorus, potassium, sodium and vitamins D and K; their interactions, physiological ratios and synergism/antagonism are discussed as well. In conclusion, calcium, magnesium and vitamin D have a profound impact on OSA and its components, and the latter two also on LGCI. Potassium and vitamin K are vital in bone, muscle functioning and possibly adipose tissue modification. Both, but particularly vitamin D, surfaced as important modulators of immune system with application in COVID-19 infections. While both phosphorus and sodium have important roles in bone, muscle and can impact adiposity, due to their abundance in food, their intake should be curbed to prevent possible damaging effects.

Assessment of Body Composition and Dietary Intake in Nursing-Home Residents: Could Lessons Learned from the COVID-19 Pandemic Be Used to Prevent Future Casualties in Older Individuals?
Keser, I, Cvijetić, S, Ilić, A, Colić Barić, I, Boschiero, D, Ilich, JZ
Nutrients. 2021;(5)
Abstract
The population of older adults, especially those living in the nursing homes, is growing. The sedentary lifestyle and possible poor nutrition in nursing homes place residents (NHRs) at risk for body composition impairments, malnutrition, and, subsequently, numerous chronic diseases. The aim of this study was to assess body composition (including body fluids) and dietary intake in NHRs. The association between osteosarcopenic adiposity syndrome (OSA) and its components, osteopenic adiposity (OA), sarcopenic adiposity (SA), and adiposity-only (AD), and specific macro- and micro-nutrients was evaluated as well. The study included 84 participants (82.1% women), aged 65.3-95.2 years. Body composition was assessed with an advanced bioelectrical impedance device BIA-ACC® and dietary intake was assessed via 24-h recall and analyzed using "Nutrition" software. The majority (95%) of participants were overweight with a high body fat and low muscle and bone mass, leading to a high prevalence of OSA (>50%), OA (13%), and AD (26%). There were only a few participants with SA, and they were not analyzed. The highest extracellular water/total body water ratio was observed in the OSA participants, indicating a heightened inflammatory state. Participants in all three body composition categories had a similar nutrient intake, with protein, fiber, omega-3 fatty acids, and almost all micronutrients being far below recommendations. In conclusion, a high prevalence of OSA among NHRs accompanied by a poor dietary intake, could place these residents at a very high risk for COVID-19 infections. Therefore, optimization of body composition and nutritional status should be included along with standard medical care in order to provide better health maintenance, particularly in the COVID-19 era.

Ilich, JZ, Gilman, JC, Cvijetic, S, Boschiero, D
Nutrients. 2020;(4)
Abstract
Chronic stress and low-grade chronic inflammation (LGCI) are key underlying factors formany diseases, including bone and body composition impairments. Objectives of this narrativereview were to examine the mechanisms by which chronic stress and LGCI may influenceosteosarcopenic adiposity (OSA) syndrome, originally named as ostoesarcopenic obesity (OSO).We also examined the crucial nutrients presumed to be affected by or cause of stress andinflammation and compared/contrasted them to those of our prehistoric ancestors. The evidenceshows that stress (particularly chronic) and its related inflammatory processes, contribute toosteoporosis, sarcopenia, and adiposity ultimately leading to OSA as a final and most derangedstate of body composition, commencing at the mesenchymal cell lineage disturbance. Thefoods/nutrients consumed by modern humans, as well as their altered lifestyle, also contribute tostress, LGCI and subsequently to OSA. The processes can also go in opposite direction when stressand inflammation impact nutritional status, particularly some micronutrients' levels. Whilenutritional management of body composition and LGCI have been studied, the nutrients (and theirquantities) most affected by stressors and those which may act toward the alleviation of stressfulstate, ultimately leading to better body composition outcomes, need to be elucidated.

Abstract
INTRODUCTION Church-based interventions have been shown to improve the dietary health of underserved populations, yet few studies have examined sustainability of health behavior change over time. This paper examines dietary outcomes over a 24-month period (baseline and 6, 18, and 24 months) for fruit and vegetable and fat consumption behaviors of African-American participants in the Health for Hearts United church-based intervention in North Florida. STUDY DESIGN This quasi-experimental, longitudinal trial was conducted from 2009 to 2012. Data were analyzed in 2018. SETTING/PARTICIPANTS Six churches in a 2-county area (3 treatment, 3 comparison) were selected for the study using community-based participatory research approaches. Participants were African-American adults (aged ≥45 years; n=211 at baseline) randomly selected from the churches, stratified by age and sex. INTERVENTION Health for Hearts United intervention was developed by the 3 treatment churches. The 18-month intervention was implemented in 3 6-month phases, framed around 3 conceptual components, which included 4 types of programs and 4 key messages. MAIN OUTCOME MEASURES Fruit and vegetable consumption was assessed using a single item (fruit and vegetable intake) and the National Cancer Institute Fruit and Vegetable Screener. Fat consumption was determined using a single item (fat intake) and the National Cancer Institute Fat Screener. Background characteristics included age, sex, educational level, and marital status. RESULTS Significant time effects only were found for daily fruit and vegetable intake (p<0.001), fat intake (p<0.001), and the Fat Screener (p<0.001) with dietary improvements in both treatment and comparison groups across the intervention phases. Fruit and Vegetable Screener results showed that time (p<0.001) and the interaction between time and treatment (p<0.01) were significant, with increases in fruit and vegetable consumption over time for both the treatment and comparison groups and with the increase differing between groups. Post hoc analysis revealed that the treatment group had greater increases in fruit and vegetable consumption than the comparison group between Phases 1 and 3 (p=0.03). CONCLUSIONS Dietary behaviors of mid-life and older African Americans can be improved and sustained over 24 months using a church-based heart health intervention, with similar improvements noted for both comparison and treatment participants. TRIAL REGISTRATION This study is registered at www.clinicaltrials.govNCT03339050.

Osteosarcopenic Obesity: Current Knowledge, Revised Identification Criteria and Treatment Principles.
Kelly, OJ, Gilman, JC, Boschiero, D, Ilich, JZ
Nutrients. 2019;(4)
Abstract
Osteosarcopenic obesity (OSO) syndrome describes the simultaneous deterioration of bone, muscle and excess fat, resulting in reduced functionality and systemic metabolic dysregulation. The key component contributing to this may be ectopic fat in the viscera, bone and muscle. OSO research to date is summarized, and the revised criteria for its identification for research purposes are reviewed and proposed, including new criteria to assess visceral fat in males and females. Finally, nutritional and physical activity recommendations are consolidated into a treatment algorithm, which can be validated in future studies and which may also be applied to preventative management.

Plain language summary
A woman’s menopausal years are believed to bring about weight gain due to various biological mechanisms, such as depletion of oestrogen. Many women undertake weight loss diets, in an attempt to control the weight gain, and although weight loss can reduce the risk factors for metabolic and cardiovascular disease etc, it can also lead to accelerated loss bone density and muscle mass. The objective of this study was to investigate whether by complementing a low-calorie diet with 4 to 5 servings of low-fat dairy foods per day and/or supplementing with calcium and vitamin D supplements would aid weight loss and preserve either/both bone and muscle mass. The study was conducted on 189 early postmenopausal, obese women. It was a randomized, placebo-controlled clinical trial conducted over 6 months. Researchers found that results were better for the participants on the low-fat dairy foods and those supplementing with calcium and vitamin D when compared to the placebo group (who only had placebo pills). They suggest that when embarking on a weight loss program it is beneficial to include 4 to 5 servings of low-fat dairy foods each day and take calcium and vitamin D supplements will have a positive impact on weight loss, bone density and muscle mass in post-menopausal women.
Abstract
Several studies have investigated the possibility of dairy foods and calcium (Ca) mediating weight and body composition, but a consensus has not been reached. We aimed to investigate weight-loss-related outcomes during intervention with low-fat dairy foods or Ca + vitamin D supplements, both as complements to hypocaloric diets. Overweight/obese Caucasian, early-postmenopausal women (n = 135) were recruited for a 6 month energy-restricted weight loss study complemented with either low-fat dairy foods (D; 4-5 servings/day), or Ca + vitamin D supplements (S); both to amount a total of ~1500 mg/day and 600 IU/day of Ca and vitamin D, respectively, or placebo pills (C). Bone mineral density (BMD) and lean and fat tissue were measured by Lunar iDXA. Serum and urinary markers of bone turnover were analyzed. Diet and physical activity were assessed with 3-day records. Participants on average lost ~4%, ~3%, and ~2% of body weight, fat, and lean tissue, respectively. The significantly better outcomes were noticed in participants in the D group regarding body composition (fat loss/lean tissue preservation) and in participants in the S group regarding the BMD outcomes, compared to those in the C group. Therefore, increasing low-fat dairy foods to 4-5 servings/day and/or increasing Ca & vitamin D intake by supplements (in those who are at the borderline dietary intake) may be beneficial for weight loss/maintenance and may lead to more favorable bone and body composition outcomes in postmenopausal women during moderate weight loss.

Abstract
This study examined lower life satisfaction, active coping and cardiovascular disease risk factors (diastolic and systolic blood pressure, body mass index, and circumferences) in older African Americans over the phases of an 18-month church-based intervention, using a quasi-experimental design. Participants (n = 89) were 45 years of age and older from six churches (three treatment, three comparison) in North Florida. Lower life satisfaction had a persistent unfavorable effect on weight variables. Active coping showed a direct beneficial effect on selected weight variables. However, active coping was adversely associated with blood pressure, and did not moderate the association between lower life satisfaction and cardiovascular risk factors. The intervention had a beneficial moderating influence on the association between lower life satisfaction and weight variables and on the association between active coping and these variables. Yet, this pattern did not hold for the association between active coping and blood pressure. The relationship of lower life satisfaction and selected cardiovascular risk factors and the positive effect of active coping were established, but findings regarding blood pressure suggest further study is needed.

Macronutrient Intake and Distribution in the Etiology, Prevention and Treatment of Osteosarcopenic Obesity.
Kelly, OJ, Gilman, JC, Kim, Y, Ilich, JZ
Current aging science. 2017;(2):83-105
Abstract
BACKGROUND Osteosarcopenic obesity, the combined deterioration of bone, muscle and fat tissues, could become the ultimate trajectory of aging. Aging stem cells are deregulated by low-grade chronic inflammation and possibly by diet. The metabolic shift of stem cells towards adipogenesis results in osteo obesity, sarco obesity and obesity. Macronutrients have numerous physiological functions but are regarded mainly for their energy contribution. Currently, no nutritional causes or treatment/prevention guidelines exist for osteosarcopenic obesity. OBJECTIVE The aim of this review is to assemble the evidence to elucidate if the macronutrient composition of the Western diet has an effect on the development of osteosarcopenic obesity. In view of the role of brain in locomotion a section examining the macronutrients as possible modulators of brain functioning was included. METHOD An extensive literature search of PubMed and Medline was conducted for human data using combinations and synonyms of osteoporosis, sarcopenia and obesity, and energy, carbohydrate, protein and lipid, and brain. US National Health and Nutrition Examination Survey (NHANES) food intake data from 2002-2012 were obtained and transposed to Microsoft Excel for analysis. RESULTS NHANES data showed that energy imbalances in aging, excess high glycemic carbohydrate, lower protein intakes and low long chain polyunsaturated fat intakes may contribute to osteosarcopenic obesity. 135 articles were included in the review. CONCLUSION Early humans probably consumed a diet closer to what the human body was designed for; however, we do not know the ideal energy and macronutrient proportions for optimal health or for preventing/treating aging and osteosarcopenic obesity.
