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]

Vitamin D deficiency is associated with poor bone health, colorectal cancer, type 1 diabetes and multiple sclerosis. Two national health-related societies in Canada have made recommendations for vitamin D supplementation, yet little research has been reported on the vitamin D status of Canadians. Lifestyle changes, such as sunscreen use, spending less time outdoors and insufficient intake of vitamin D-containing foods as well as northern latitude, may be affecting human vitamin D status. A cross-sectional analysis of 25-hydroxyvitamin D [25-(OH)D] was conducted in pregnant women, newborns (umbilical cord blood) and children. Samples were analysed by liquid chromatography mass spectrometry. Published ranges for 25-(OH)D were used to determine vitamin D status. The prevalence of 25-(OH)D deficiency for the three groups studied revealed most concentrations in the 25-(OH)D deficiency or insufficiency ranges. There were significant differences in all groups studied between seasons, with the exception of maternal blood and female cord blood samples. 25-(OH)D insufficiency was common in all groups for winter and summer, more so in winter. 25-(OH)D insufficiency was common in the three groups studied. The Newfoundland and Labrador population may be at increased risk for vitamin D insufficiency because of factors such as northern latitude and lifestyle issues. Further research on the vitamin D status of this population is important, considering the potential adverse health-related outcomes and the recommendations on supplementation being made.

The Canadian International Food Security Research Fund programme supported research and scaling up of nutrition‐ and gender‐sensitive agriculture innovations from 2009 to 2018. Women and girls were identified as agents of change and were targeted as the main programme beneficiaries. Projects were implemented in 25 countries through multistakeholder partnerships among universities, research institutions, public and private sectors, and civil society groups, reaching over 78 million people, mainly women and children. Approaches specific to nutrition included growing more nutritious crops, improving dietary diversity, value added processing, food fortification, and nutrition education. Scale‐up for impact was achieved through a number of pathways that started with evidence through rigorous research, followed by a combination of elements such as understanding local and regional contexts to identify specific bottlenecks and opportunities for the deployment and adoption of successful innovations, selecting politically effective or influential partners to lead the scaling up process, and investing in long‐term local capacity and leadership building. Overall, the knowledge generated in the programme indicate that well‐designed nutrition‐sensitive agriculture and food‐based interventions can have meaningful impacts on pathways that will lead to better health and well‐being of women and children through improving household and individual access to nutrient‐rich foods. Longer intervention times are needed to demonstrate changes in health indicators such as reduced stunting. This overview paper summarises the programme and showcases examples from studies that demonstrate the impact pathway for nutrition interventions that encompass efficacy and effectiveness studies, value‐added processing, cost effectiveness of interventions, and bringing a proven intervention to scale.
