Purpose To determine the relationship between children’s average long-term exposure to maternal depressive symptoms age 1 month to Grade 6 and adolescents’ body mass index (BMI) z-score at age 15 mediated by the adolescents’ depressive symptom experience. Methods A total of 1,364 infants and their families from the Eunice Kennedy Shriver National Institute of Child Health and Human Development Study of Early Child Care and Youth Development were recruited. Results Mediation analyses revealed a significant relationship between children’s average long-term exposure to maternal depressive symptoms from age 1 month to Grade 6 and adolescents’ BMI z-score at age 15 (total effect = 0.015, p = .013, 95% confidence interval (CI): 0.0032, 0.027). The adolescents’ experience of depressive symptoms significantly mediat...

This study evaluates the effect of AHA dietary counselling on fat intake. Between 2009 and 2014, 119 obese adults with metabolic syndrome (MetS), (71% women, average 52.5 years of age, and 34.9 kg/m² of body mass index), received individual and group counselling on the AHA diet, over a one-year study period. Each participant attended 2 individual sessions (months 1 and 12) and 12 group sessions, at one-month intervals. At baseline and one-year, we collected three random 24-h diet recalls (two weekdays and one weekend day). Fat intake patterns over time were analyzed using paired- test and linear mixed-effect models. There was significant variation on SFA and TFA intake per meal, being highest at dinner, in restaurants, and on weekends. Over the one-year study period, daily intake of total ...

Findings in Western populations suggest that smoking may cluster with other health-risk behaviors. To explore these relationships in Chinese male adults, we utilized baseline data from the China Seven Cities Study (CSCS). Male adults (n = 12,122) were included. Smoking status was defined as never smokers, ex-smokers, current smokers, and current heavy smokers. Logistic regression was employed to investigate the association of cigarette smoking and patterns of food consumption, physical activity, and alcohol drinking. After controlling for age, socioeconomic status, and city residence, heavy smokers consumed significantly less vegetables, fruits, milk and other dairy products, spent significantly more time watching television, slept and exercised less, and got drunk or engaged in binge drinking more frequently compared to never, ex-, or cu...

A longitudinal analysis was performed using data from the China Seven Cities Study, a health promotion and smoking prevention study conducted in seven cities across Mainland China between 2002 and 2005. Participants included 5,020 middle and high school students and their parents. Explanatory variables included foreign media exposure, attitude toward appearance, parent education, and family income. Three-level, random-effect models were used to predict general adiposity (i.e., body mass index) and central adiposity (i.e., waist circumference). The Generalized Estimating Equation approach was utilized to determine the effect of explanatory variables on overweight status. Among girls, foreign media exposure was significantly negatively associated with general adi...

To investigate relationships between overweight status, weight perception patterns, and weight management goals and practices in Chinese female college students. A cross-sectional analysis was conducted with data from 902 female subjects aged 18 to 25 years participating in the China Seven Cities Study, a health promotion and smoking prevention study conducted in mainland China in 2003. Logistic regression models were used to explore associations between overweight status, weight perception, specific weight management goals and practices, and current levels of vigorous-intensity physical activity and food consumption. Based on World Health Organization standards for Asian adults, 16.7% of college females were o...
