The Association between Adult Sport, Fitness, and Recreational Physical Activity and Number and Age of Children Present in the Household: A Secondary Analysis Using NHANES.

Only one in three adults in the United States meets the weekly recommendation for physical activity (PA). The presence of children in the home may restrict adult PA. The purpose of this study was to examine the association between adult moderate and vigorous sport, fitness, and recreational physical activities and the number and age (0-5 and 6-17) of children in their household. Secondary data were drawn from the National Health and Nutrition Examination Survey (NHANES) from 2007-2016. Adults with complete survey data for self-reported moderate (MPA) and vigorous physical activities (VPA), number of children in the home, and other sociodemographic variables were included. The final sample included 2034 adults from 22-65 years of age. Analyses included ANOVAs and separate multivariable regression analyses to determine if the number of children in the household aged 0-5 and 6-17 were significant predictors of weekly moderate-to-vigorous physical activity (MVPA) after controlling for covariates. For MPA, no differences were found between adult PA regardless of the number and age of children in the home. For VPA, adults with two or more children aged 0-5 reported 80 fewer minutes of weekly VPA (p < 0.05) compared to those with no children or just one child in this age group after controlling for all covariates. Finally, adults with three or more children in the household aged 6-17 reported fifty fewer minutes of weekly VPA (p < 0.05) compared to those with no children, one, or just two in the household. These findings highlight a need to support the vigorous PA behaviors of this population, as the majority of the family-based PA intervention studies to date have primarily focused on family dyads.

Design and Implementation of a Nutrition and Breastfeeding Education Program for Black Expecting Mothers and Fathers.

OBJECTIVE: To describe the intervention and research methods of Project Dads in Nutrition Education, an intervention that adds nutrition and breastfeeding education to the existing Healthy Start program in Georgia for Black expecting mothers and fathers to improve nutrition literacy, health outcomes, and breastfeeding rates. DESIGN: This 2-year community-based participatory research study employs a cluster randomization factorial design. SETTING: Six Healthy Start program sites (3 intervention and 3 control sites) in Georgia counties with high infant and maternal mortality rates. PARTICIPANTS: Approximately 480 Black, expecting, Healthy Start program participants (20 couples [mother and father] and 40 single mothers from each site) will be enrolled over the study period. INTERVENTION(S): Project Dads in Nutrition Education will strengthen the capacity of the Georgia Healthy Start program to integrate an evidence-based nutrition education program, breastfeeding education, and father engagement into its routine services. MAIN OUTCOME MEASURE(S): Changes in prepost survey assessment of participants' nutrition literacy and eating behaviors; changes in prepost survey assessment of participants' breastfeeding knowledge, attitudes, intent, initiation, and duration; and health and food diary collected 3 times (ie, at baseline, 3 months, and 6 months after enrollment). ANALYSIS: Process evaluation throughout the study to document implementation. Generalized linear mixed modeling will be used to determine the impact of the intervention.

The weight loss blogosphere: an online survey of weight loss bloggers.

Blogging is a form of online journaling that has been increasingly used to document an attempt in weight loss. Despite the prevalence of weight loss bloggers, few studies have examined this population. We examined characteristics of weight loss bloggers and their blogs, including blogging habits, reasons for blogging, like and dislikes of blogging, and associations between blogging activity and weight loss. Participants (N = 194, 92.3 % female, mean age = 35) were recruited from Twitter and Facebook to complete an online survey. Participants reported an average weight loss of 42.3 pounds since starting to blog about their weight loss attempt. Blogging duration significantly predicted greater weight loss during blogging (ß = -3.65, t(185) = -2.97, p = .003). Findings suggest that bloggers are generally successful with their weight loss attempt. Future research should explore what determines weight loss success/failure in bloggers and whether individuals desiring to lose weight would benefit from blogging.
