Physical activity levels of urban and rural young children in the Iowa Bone Development Study
A better understanding of the association of the environment to young children’s physical activity is needed to design effective behavioral interventions and to improve communities' infrastructures in ways that support the development of healthy behaviors. This thesis used data from the Iowa Bone Development Study (IBDS) to examine activity behaviors of young children in urban and rural Iowa. M...
متن کاملTracking of TV and video gaming during childhood: Iowa Bone Development Study
BACKGROUND Tracking studies determine the stability and predictability of specific phenomena. This study examined tracking of TV viewing (TV) and video game use (VG) from middle childhood through early adolescence after adjusting for moderate and vigorous physical activity (MVPA), percentage of body fat (% BF), and maturity. METHODS TV viewing and VG use were measured at ages 5, 8, 11, and 13...
متن کاملChildhood socioeconomic status and adult femoral neck bone strength: findings from the Midlife in the United States Study.
PURPOSE Bone acquisition in childhood impacts adult bone mass, and can be influenced by childhood socioeconomic conditions. Socioeconomic status is also associated with body weight which affects the load that bone is exposed to in a fall. We hypothesized that socioeconomic advantage in childhood is associated with greater bone strength relative to load in adulthood. METHODS Hip dual x-ray abs...
متن کاملMuscular development and physical activity as major determinants of femoral bone mass acquisition during growth.
OBJECTIVES To investigate to what extent bone mass accrual is determined by physical activity and changes in lean, fat, and total body mass during growth. METHODS Twenty six physically active and 16 age matched control boys were followed up for three years. All subjects were prepubertal at the start of the survey (mean (SEM) age 9.4 (0.3) years). The weekly physical activity of the active boy...
متن کاملActive lifestyle in childhood and adolescence prevents obesity development in young adulthood: Iowa Bone Development Study
OBJECTIVE To test the hypothesis that individuals who are active but who decrease physical activity (PA) over time have a higher risk of becoming obese in young adulthood, when compared to individuals who are consistently active throughout childhood and adolescence. METHODS Iowa Bone Development Study cohort members (242 males and 251 females) participated in accelerometry assessments, dual-e...
