Background/objectives: Sedentary behavior (SB), defined as sitting (nonexercising), reclining, and lying down (posture), or by low energy expenditure, is a public health risk independent to physical activity. The objective of this systematic literature review was to synthesize the available evidence on amount of SB reported by and measured in older adults. Data source: Studies published between 1981 and 2014 were identified from electronic databases and manual searching. Large-scale population studies/surveys reporting the amount of SB (objective/ subjective) in older adults aged ≥ 60 years of age were included. Appraisal and synthesis was completed using MOOSE guidelines. Results: 349,698 adults aged ≥ 60 within 22 studies (10 countries and 1 EU-wide) were included. Objective measurement of SB shows that older adults spend an average of 9.4 hr a day sedentary, equating to 65-80% of their waking day. Self-report of SB is lower, with average weighted self-reports being 5.3 hr daily. Within specific domains of SB, older adults report 3.3 hr in leisure sitting time and 3.3 hr watching TV. There is an association with more time spent in SB as age advances and a trend for older men to spend more time in SB than women. Conclusion/ implications: Time spent sedentary ranges from 5.3-9.4 hr per waking day in older adults. With recent studies suggesting a link between SB, health, and well-being, independent of physical activity, this is an area important for successful aging. Limitations: Different methodologies of measurement and different reporting methods of SB made synthesis difficult. Estimated SB time from self-report is half of that measured objectively; suggesting that most self-report surveys of SB will vastly underestimate the actual time spent in SB. [ABSTRACT FROM AUTHOR]

This study aimed to examine the association between breastfeeding and childhood obesity. A multinational cross‐sectional study of 4,740 children aged 9–11 years was conducted from 12 countries. Infant breastfeeding was recalled by parents or legal guardians. Height, weight, waist circumference, and body fat were obtained using standardized methods. The overall prevalence of obesity, central obesity, and high body fat were 12.3%, 9.9%, and 8.1%, respectively. After adjustment for maternal age at delivery, body mass index (BMI), highest maternal education, history of gestational diabetes, gestational age, and child's age, sex, birth weight, unhealthy diet pattern scores, moderate‐to‐vigorous physical activity, sleeping, and sedentary time, exclusive breastfeeding was associated with lower odds of obesity (odds ratio [OR] 0.76, 95% confidence interval, CI [0.57, 1.00]) and high body fat (OR 0.60, 95% CI [0.43, 0.84]) compared with exclusive formula feeding. The multivariable‐adjusted ORs based on different breastfeeding durations (none, 1–6, 6–12, and > 12 months) were 1.00, 0.74, 0.70, and 0.60 for obesity (Ptrend =.020) and 1.00, 0.64, 047, and 0.64 for high body fat (Ptrend =.012), respectively. These associations were no longer significant after adjustment for maternal BMI. Breastfeeding may be a protective factor for obesity and high body fat in 9‐ to 11‐year‐old children from 12 countries. [ABSTRACT FROM AUTHOR]

Developing culturally appropriate diabetes nutrition interventions for immigrants could be facilitated knowing what is successful in the home country and other relevant countries. The primary purpose of this scoping review was to identify the design and delivery methods of nutrition interventions for Chinese populations with type 2 diabetes, in their home countries and as immigrants to western countries. A total of 14 articles was retrieved and included. Overall, the approaches used in China often were modelled on intensive lifestyle programs although alternative strategies were also identified. Most interventions were not focussed solely on nutrition, and only a few were conducted in community settings. Most of the interventions were delivered in a group format, while those conducted in China also included individual counselling, particularly for nutrition. In addition, the diabetes and nutrition-related outcomes, cultural relevance and acceptability, and other factors that influenced protocol compliance were considered. Improvements in blood glucose control were observed in participants in all interventions where it was measured. Participants reported increased nutritional knowledge but nutritional behaviour was generally not well documented. Trials conducted in the United States emphasized the importance of cultural adaptation of intervention programs, particularly with respect to dietary patterns and specific foods. Practice-transferable characteristics are highlighted. Research gaps included trials conducted in community settings with pragmatic implementation and evaluation, comparative trials of interventions to gauge relative effectiveness, and measuring and reporting dietary outcomes for better understanding of the impact on dietary behaviours and their relationship to health outcomes.
