Background Recent longitudinal work suggests that weight change is an important risk factor for inflammation across the full range of BMI . However, few studies have examined whether the risk of inflammation differs by patterns of weight gain over time. Using latent class trajectory analysis, we test whether patterns of weight gain are associated with elevated high‐sensitivity C‐reactive protein (hs‐ CRP 2–10 mg/L). Methods and Results Data come from China Health and Nutrition Survey ( CHNS ) participants (n=5536), aged 18 at baseline to 66 years in 2009, with measured weight over 18 years. Latent class trajectory analysis was used to identify weight‐change trajectories in 6 age and sex strata. Multivariable general linear mixed‐effects models fit with a logit link were used to assess the risk of elevated hs‐ CRP across weight trajectory classes. Models were fit within age and sex strata, controlling for baseline weight, adult height, and smoking, and included random intercepts to a...

Background: Cohort analyses suggesting that breast-feeding pro- tects against being overweight have been criticized for inadequately controlling for confounding associated with the self-selection of feeding practices. Methods: Using nationally representative U.S. data from the Na- tional Longitudinal Study of Adolescent Health (1994 -1996), we performed traditional cohort analyses (n 11,998) using logistic regression to estimate the relation between breast-feeding and

To qualitatively and quantitatively examine body image ideals and perceived weight-related health among African-American girls and their female caregivers to inform intervention development for Girls Rule!, an obesity prevention pilot program. Formative study using qualitative data from semi-structured interviews and validated quantitative body image silhouette assessment among girls (N=47) and caregivers (N=44). The participants were a convenience sample of African-American church members from North Carolina. Differences were evaluated between perceived: 1) current and ideal body size; 2) current and unhealthy body size; and 3) ideal and unhealthy body size. Thirty-seven percent of the girls and 77% of the caregivers were overweight or obese. Three body image themes emerged from the qualitative interviews: 1) being fat is unhealthy; 2) caregivers are role models (positive and negative) for body image ideals; and 3) smaller body size is important for wearing fashionable clothing. A ...

BMI is highly correlated between spouses; however, less is understood about the underlying mechanism(s) by which the development of obesity in one individual increases the risk of obesity in his/her spouse. The objective of this study is to investigate whether romantic partnership and duration of cohabitation are related to incident obesity and obesity-promoting behaviors. We used two data sets from the National Longitudinal Study of Adolescent Health: (i) 6,949 US adolescents (wave II, 1996) followed into adulthood (wave III, 2001-2002) and (ii) 1,293 dating, cohabiting, and married romantic couples from wave III, including measured anthropometry and self-report behavior data. In the longitudinal cohort, we used sex-stratified logistic regression models to examine the risk of incident obesity by longitudinal romantic relationship status and duration of time spent living with a romantic partner. In the Couples Sample, we used multinomial logistic regression to predict concordance in outcomes: obesity, moderate-to-vigorous physical activity, and screen time by romantic partnership and duration of time living with a romantic partner. Individuals who transitioned from single/dating to cohabiting or married were more likely to become obese than those who were dating at both waves. Partner concordance for negative, obesity-related behaviors was strongest for married couples and couples who lived together > or =2 years. The shared household environment may increase the likelihood of becoming obese, influence partner concordance, and may be an important target for obesity intervention.
