The purpose was to investigate a possible levelling off in the obesity epidemic, by systematically reviewing literature and web-based sources. Eligible studies and data sources were required to have at least two measures of obesity prevalence since 1999. A literature and Internet search resulted in 52 studies from 25 different countries. The findings(More)
The severity of the long term consequences of the current childhood obesity epidemic on coronary heart disease is unknown. Therefore we investigated the association between body mass index (BMI) at ages 7-13 years and heart disease in adulthood among 276,835 Danish schoolchildren. We found that higher BMI during this period of childhood is associated with(More)
BACKGROUND Weight gained during pregnancy and not lost postpartum may contribute to obesity in women of childbearing age. OBJECTIVE We aimed to determine whether breastfeeding reduces postpartum weight retention (PPWR) in a population among which full breastfeeding is common and breastfeeding duration is long. DESIGN We selected women from the Danish(More)
BACKGROUND Small birth size may be associated with increased risk of cardiovascular diseases (CVD), whereas large birth size may predict increased risk of obesity and some cancers. The net effect of birth size on long-term mortality has only been assessed in individual studies, with conflicting results. METHODS The Meta-analyses of Observational Studies(More)
BACKGROUND Small size at birth is associated with subsequent cardiovascular disease and diabetes, and large size is associated with obesity and cancer. The overall impact of these opposing effects on mortality throughout the lifespan is unclear because causes of death change with age. METHODS We investigated the association of birth weight with adult(More)
For some women, pregnancy may increase the risk of future obesity with consequences for health and well-being. Psychosocial factors may be partly responsible for this. The aim of this study was to examine the association between psychosocial factors during pregnancy and postpartum weight retention (PPWR) at 6 and 18 months. A total of 37,127 women in The(More)
High breast density, a strong predictor of breast cancer may be determined early in life. Childhood anthropometric factors have been related to breast cancer and breast density, but rarely simultaneously. We examined whether mammographic density (MD) mediates an association of birth weight, childhood body mass index (BMI), and height with the risk of breast(More)
BACKGROUND Although both maternal prepregnancy body mass index (BMI) and gestational weight gain (GWG) may affect birth weight, their separate and joint associations with complications of pregnancy and delivery and with postpartum weight retention are unclear. OBJECTIVES We aimed to investigate the combined associations of prepregnancy BMI and GWG with(More)
BACKGROUND Women who are overweight or obese before pregnancy breastfeed for shorter durations than do normal-weight women. These shorter durations may place infants of overweight and obese women at risk of not receiving the benefits of breastfeeding, which may include a reduced risk of overweight later in life. OBJECTIVE We examined how maternal(More)
BACKGROUND Obesity in late adolescence has been associated with an increased risk of multiple sclerosis (MS); however, it is not known if body size in childhood is associated with MS risk. METHODS Using a prospective design we examined whether body mass index (BMI) at ages 7-13 years was associated with MS risk among 302,043 individuals in the Copenhagen(More)
