OBJECTIVE The role of sugar-sweetened beverages (SSBs) in promoting obesity is controversial. Observational data link SSB consumption with excessive weight gain; however, randomized, controlled trials are lacking and necessary to resolve the debate. We conducted a pilot study to examine the effect of decreasing SSB consumption on body weight. METHODS We(More)
OBJECTIVES To determine relationships between physical fitness and academic achievement in diverse, urban public school children. METHODS This cross-sectional study used public school data from 2004 to 2005. Academic achievement was assessed as a passing score on Massachusetts Comprehensive Assessment System (MCAS) achievement tests in Mathematics(More)
BACKGROUND Consumption of sugar-sweetened beverages may cause excessive weight gain. We aimed to assess the effect on weight gain of an intervention that included the provision of noncaloric beverages at home for overweight and obese adolescents. METHODS We randomly assigned 224 overweight and obese adolescents who regularly consumed sugar-sweetened(More)
The objective of this study was to assess the impact of a community-based healthy weight intervention on child weight and fitness. Cambridge Public Schools (CPS) have monitored BMI and fitness annually since 2000. Annual increases of overweight and obesity from 2000 (37.0%) to 2004 (39.1%), triggered a multidisciplinary team of researchers, educators,(More)
OBJECTIVES We examined the relationship between comprehensive fitness tests and overweight using a school surveillance system in a racially diverse city in the United States. RESEARCH METHODS AND PROCEDURES Trained physical education teachers measured weight, height, and fitness annually from 2001 to 2003. We compiled data for a cross-sectional analysis(More)

OBJECTIVE To determine the relationship between serum vitamin D levels and cardiometabolic risk factors independent of adiposity in urban schoolchildren. STUDY DESIGN We assessed the relationships among serum 25-hydroxyvitamin D [25(OH)D], adiposity measured by body mass index (BMI) z-score (BMIz), and 6 cardiometabolic risk factors (total cholesterol,(More)
OBJECTIVES To monitor annual changes in weight status, we determined incidence and remission rates of overweight among school-aged children with longitudinal school-based surveillance. METHODS We estimated 1-year changes in weight status among students enrolled in public schools in Cambridge, Mass. Physical education teachers measured height and weight(More)
BACKGROUND As overweight continues to rise among children, schools seek effective and sensitive ways to engage parents in promoting healthy weight. OBJECTIVE To evaluate a school-based health report card on the family awareness of and concern about the child weight status, plans for weight control, and preventive behaviors. DESIGN Quasi-experimental(More)
Aerobic fitness has been shown to have several beneficial effects on child health. However, research on its relationship with academic performance has been limited, particularly in developing countries and among undernourished populations. This study examined the association between aerobic fitness and academic achievement in clinically healthy but(More)
