Abstract
Digital health interventions have been shown to be clinically-effective for type 2 diabetes mellitus (T2DM) and hypertension prevention and treatment. This study synthesizes and compares the cost-effectiveness of text-messaging, smartphone application, and websites by searching CINAHL, Cochrane Central, Embase, Medline and PsycInfo for full economic or cost-minimisation studies of digital health interventions in adults with or at risk of T2DM and/or hypertension. Costs and health effects are synthesised narratively. Study quality appraisal using the Consensus on Health Economic Criteria (CHEC) list results in recommendations for future health economic evaluations of digital health interventions. Of 3056 records identified, 14 studies are included (7 studies applied text-messaging, 4 employed smartphone applications, and 5 used websites). Ten studies are cost-utility analyses: incremental cost-utility ratios (ICUR) vary from dominant to €75,233/quality-adjusted life year (QALY), with a median of €3840/QALY (interquartile range €16,179). One study finds no QALY difference. None of the three digital health intervention modes is associated with substantially better cost-effectiveness. Interventions are consistently cost-effective in populations with (pre)T2DM but not in populations with hypertension. Mean quality score is 63.0% (standard deviation 13.7%). Substandard application of time horizon, sensitivity analysis, and subgroup analysis next to transparency concerns (regarding competing alternatives, perspective, and costing) downgrades quality of evidence. In conclusion, smartphone application, text-messaging, and website-based interventions are cost-effective without substantial differences between the different delivery modes. Future health economic studies should increase transparency, conduct sufficient sensitivity analyses, and appraise the ICUR more critically in light of a reasoned willingness-to-pay threshold.Registration: PROSPERO (CRD42021247845).

Abstract
Evidence suggests that low carbohydrate dietary (LCD) approaches can improve glycaemic control and may result in type 2 diabetes mellitus (T2DM) remission. This systematic literature review (SLR) aimed to assess the effectiveness of technology-enabled LCD interventions in the management of people with prediabetes or T2DM. Data sources included Medline, Embase, CINAHL, and Web of Science. Randomised (RCTs) or non-randomised (non-RCTs) controlled trials investigating the effect of technology-enabled LCDs (<130 g/day) or very low carbohydrate diets (VLCDs < 50 g/day) on glycosylated haemoglobin A1c (HbA1c) for at least three months and published in English between 2009 and 2023 were included. Risk of bias assessment, data extraction, and synthesis were conducted using standard tools and procedures. Six studies (two RCTs and four non-RCTs, total sample, n = 1519) were identified and included in the SLR. Two studies examining LCDs reported significant reductions in mean HbA1c (0.4% and -1.2%) and weight loss (-3.8 kg and -7.5 kg) at one year. Three studies examining VLCDs reported significant reductions in mean HbA1c (-0.8% to -1.3%) and weight loss (-12 kg to -14 kg) up to two years. Technology-enabled LCD or VLCD interventions can be a novel approach in helping people with prediabetes or T2DM self-manage their condition and possibly achieve remission. However, further research is required to determine the sustainability, effectiveness, and safety of this approach.

Nutrients. 2022;(23)
Abstract
Maternal overweight/obesity has been associated with an increased risk of obesity in childhood. We investigated the effect of maternal overweight/obesity during pre-pregnancy and whether it is a stronger predictor of child obesity, compared to maternal overweight/obesity during childhood. Prospective or retrospective cohort studies published in English, reporting on obese children and adolescents (2-18 years), with overweight/obese mothers in either pre-pregnancy or during childhood were included. A search was conducted from 2012 to April 2022 in MEDLINE, Web of Science, CINAHL, and EMBASE, followed by screening, data extraction, quality assessment and narrative synthesis. Eleven eligible studies (9 prospective and 2 retrospective cohort studies; total sample, n = 27,505) were identified. Eight studies examined maternal overweight/obesity in pre-conception, presenting consistent positive associations with childhood obesity, three reported positive associations between childhood obesity and maternal overweight/obesity during childhood, and one presented positive associations between both maternal exposures. The narrative synthesis failed to identify which maternal exposure is the strongest predictor of childhood obesity, with studies reporting significant associations between maternal overweight/obesity and child obesity in both time points. Intervention programs aiming to reduce childhood obesity should focus on supporting women of childbearing age with weight management from preconception and throughout their life-course.

Abstract
Obesity in childhood and adolescence represents a major health problem. Novel e-Health technologies have been developed in order to provide a comprehensive and personalized plan of action for the prevention and management of overweight and obesity in childhood and adolescence. We used information and communication technologies to develop a "National Registry for the Prevention and Management of Overweight and Obesity" in order to register online children and adolescents nationwide, and to guide pediatricians and general practitioners regarding the management of overweight or obese subjects. Furthermore, intelligent multi-level information systems and specialized artificial intelligence algorithms are being developed with a view to offering precision and personalized medical management to obese or overweight subjects. Moreover, the Big Data against Childhood Obesity platform records behavioral data objectively by using inertial sensors and Global Positioning System (GPS) and combines them with data of the environment, in order to assess the full contextual framework that is associated with increased body mass index (BMI). Finally, a computerized decision-support tool was developed to assist pediatric health care professionals in delivering personalized nutrition and lifestyle optimization advice to overweight or obese children and their families. These e-Health applications are expected to play an important role in the management of overweight and obesity in childhood and adolescence.

Abstract
Clinical manifestations of cardiometabolic risk (CMR) may be set early in childhood due to unfavorable behaviors or lifestyle patterns related to diet and physical activity. Several factors may determine the adoption of such lifestyle-related behaviors, which researchers have tried to cluster under certain frameworks or models. In this context, the framework developed and proposed by this review gathers all the present knowledge regarding these determining factors to date and groups them into three main categories related to personal characteristics and the social and physical environment. Based on the proposed framework, a large variety of personal, social and physical environmental factors can positively or negatively influence CMR-related behaviors (either directly or indirectly via their interrelations), thus leading to decreased or increased risk, respectively. This framework could be of great value to public health policy makers and legislators for designing and implementing interventional programs tailored to the needs of susceptible population groups who are most in need for such initiatives. Targeting the correlates as potential determinants of CMR-related behaviors, and not just on the behaviors themselves, has been shown previously to be the most effective approach for tackling health issues related to CMR starting from early life stages.

Abstract
BACKGROUND Across Europe, poor health behaviours are associated with increased risks of non-communicable diseases. There is particular concern about young women, children and families, not least as health behaviours operating before and during pregnancy and in early postnatal life may have profound long-term consequences for children's health. Using findings drawn from 7 European countries, we aimed to identify barriers to the implementation and uptake of dietary and physical activity recommendations, and to consider how best to achieve changes in mothers' behaviours and thereby improve the adoption of health recommendations. Six studies across the 7 countries were used for this narrative synthesis of findings. KEY MESSAGES A woman's education has a strong influence on her own and her children's health behaviours. Women's diets vary across ethnic groups and according to number of children, but psychological factors, such as self-efficacy and sense of control, which may be amenable to modification, are powerful, too, particularly in women with lower educational attainment. Maternal influences on children's behaviours are strong. Differences exist in infant feeding across countries, and there are apparent urban/rural differences in children's diets and physical activity. CONCLUSIONS Interventions are needed before, as well as during, pregnancy to improve the diets of families with young children. Interventions to address psychological barriers to eating well and being more active are indicated.
