“…That PA engagement decreased less among those who were attending 4-year college and living on campus compared with those not attending school and those living at home suggests that access to and proximity of PA facilities may influence college students' engagement in PA. 29,30 Previous studies have reported differences in PA engagement according to sex and race/ethnicity, 1, 2 such as a greater decline of PA in girls than in boys. 4,6,10 In our research, without including time-varying covariates, sex was significantly associated with the linear slope of the trajectory of log MVPA (ie, MVPA over time increased for males compared with females). However, when controlling for time-varying covariates, such as PA planning and parent influences, our data indicate that male adolescents engaged in more MVPA compared with female adolescents in 10th grade (baseline) only, but sex did not influence the longitudinal curve.…”

OBJECTIVES: Examined patterns and determinants of objectively measured moderate-tovigorous physical activity (MVPA) over 4 years in US emerging adults.METHODS: Waves 1 through 4 (W1 [10th grade] to W4 data of a national cohort starting in 2010 (N = 561; 16.19 ± 0.51 years) were used. MVPA was assessed annually from accelerometers; BMI calculated from measured height/weight; and surveys ascertained self-reported physical activity (PA) planning, peer PA , family support, W1 sociodemographics, W4 school status, W4 residence, and W4 employment. Latent growth modeling estimated trajectories in log-transformed duration (minutes/day) of MVPA and associations with covariates. RESULTS:Less than 9% of participants met the recommended 60+ minutes/day MVPA across W1 through W4. W1 MVPA was greater in males versus females (B = 0.46, P < .001) and Hispanic versus White (B = 0.34, P < .001) participants. Increased BMI change (W1 to W4 slope) was associated with decreased MVPA. MVPA was positively associated with PA planning (W1-W3: B = 0.10, B = 0.06, B = 0.08, Ps < .05), but not with peer PA or family support. Participants attending 4-year college versus not-attending school (B = 0.52, P < .001), and college students living on campus versus at home (B = 0.37, P < .001) were more likely to engage in MVPA at W4. Weekend MVPA remained relatively constant from W1 through W4.CONCLUSIONS: High-school students engaged in little MVPA and maintained this low level through the transition to adulthood. Emerging adults' MVPA engagement may vary according to social contexts. Those with high BMI may benefit most from interventions to promote MVPA.

“…Studies of household food purchases also generally report a positive association between household SES and the quality and variety of purchased foods (Darmon & Drewnowski, 2008). Similarly, studies have documented an inverse association between parental BMI and rates of physical activity in adolescents (Kahn et al, 2008;Williams & Mummery, 2011), which suggests that parental BMI may serve as a proxy for other lifestyle related behaviours that are associated with rates of obesity.…”

Breastfeeding and risk of overweight and obesity at nine-years of age

Whether breastfeeding is protective against the development of childhood overweight and obesity remains the subject of considerable debate. Although a number of meta-analyses and syntheses of the literature have concluded that the greater preponderance of evidence indicates that breastfeeding reduces the risk of obesity, these findings are by no means conclusive. The present study used data from the Growing Up in Ireland study to examine the relationship between retrospectively recalled breastfeeding data and contemporaneously measured weight status for 7,798 children at nine years of age controlling for a wide range of variables including, socio-demographic factors, the child's own lifestylerelated behaviours, and parental BMI. The results of the multivariable analysis indicated that being breastfed for between 13-25 weeks was associated with a 38 percent (p<.05) reduction in the risk of obesity at nine years of age, while being breastfed for 26 weeks or more was associated with a 51 percent (p<.01) reduction in the risk of obesity at nine years of age. Moreover, results pointed towards a dose-response patterning in the data for those breastfed in excess of 4 weeks. Possible mechanisms conveying this health benefit include slower patterns of growth among breastfed children, which it is believed, are largely attributable to differences in the composition of human breast milk compared with synthesised formula. The suggestion that the choice of infant feeding method has important implications for health and development is tantalising as it identifies a modifiable health behaviour that is amenable to intervention in primary health care settings and has the potential to improve the health of the population.
