PURPOSE The effect of physical activity during pregnancy on maternal and fetal health remains controversial and studies have yet to identify the optimal dose of physical activity associated with favorable pregnancy outcomes. The aim of this study was to develop and validate a pregnancy physical activity questionnaire (PPAQ). METHODS To ascertain the type,(More)
BACKGROUND Participation in physical activity during pregnancy may reduce the risk of gestational diabetes mellitus and preeclampsia and help prevent excess maternal weight gain. However, studies describing patterns and correlates of activity during pregnancy are sparse. The purpose of this cross-sectional study was to describe total physical activity(More)
BACKGROUND The clinical utility of identifying pediatric metabolic syndrome (MetS) is controversial. This study sought to determine the status of pediatric MetS as a risk factor for adult subclinical atherosclerosis (carotid intima-media thickness [cIMT]) and type 2 diabetes mellitus (T2DM) and compare and contrast this prediction with its individual(More)
OBJECTIVE To examine overweight and obesity in Australian children followed through to adulthood. DESIGN AND PARTICIPANTS A cohort study of 8498 children aged 7-15 years who participated in the 1985 Australian Schools Health and Fitness Survey; of these, 2208 men and 2363 women completed a follow-up questionnaire at age 24-34 years in 2001-2005.

Older adults and special populations (living with disability and/or chronic illness that may limit mobility and/or physical endurance) can benefit from practicing a more physically active lifestyle, typically by increasing ambulatory activity. Step counting devices (accelerometers and pedometers) offer an opportunity to monitor daily ambulatory activity;(More)
BACKGROUND Adequate mobility is essential to maintain an independent and active lifestyle. The aim of this cross-sectional study is to examine the associations of age with temporal and spatial gait variables in a population-based sample of older people, and whether these associations are modified by sex. METHODS Men and women aged 60-86 years were(More)
BACKGROUND gait variability may be an important predictor of falls risk, but its characteristics are poorly understood. OBJECTIVE to examine the relationship between age and gait variability in a population-based sample of older people. DESIGN cross-sectional study. METHODS in people aged 60-86 years (n = 412), temporal and spatial gait variability(More)
OBJECTIVES National data indicate that Latina women are less active than non-Latina white women and are at higher risk of gestational diabetes and subsequent type 2 diabetes. Physical activity may reduce risk of maternal disorders of pregnancy, but sparse data exists on the correlates of physical activity in pregnant Latina women. METHODS We conducted a(More)
PURPOSE Participation in physical activity during pregnancy may reduce the risk of maternal and fetal disorders. However, few studies have validated physical activity questionnaires for use during pregnancy, a time characterized by different patterns of activity than nonpregnancy. Therefore, the aim of this study was to assess the validity and reliability(More)
This cross-sectional study aimed to examine the association between different body composition measures, menstrual cycle characteristics, and hormonal factors in a population-based sample of young women. The study sample included 726 Australian women aged 26-36 years who were not currently taking hormonal contraceptives and were not currently pregnant or(More)
