OBJECTIVE To estimate whether length of the first stage of labor is associated with adverse maternal and neonatal outcomes. METHODS This is a retrospective cohort study of nulliparous women with term, singleton gestations delivered in one academic center between 1990 and 2008. The length of the first stage was stratified into three subgroups: less than the 5th percentile, 5th to 95th percenti...

BACKGROUND The nutritional status of patients with cystic fibrosis (CF) is strongly associated with pulmonary function, respiratory status and survival. Malnutrition could result from a discrepancy between energy needs and food intake while malabsorption results from pancreatic insufficiency which occurs in 85% of people with CF. METHODS A quality improvement (QI) project was designed to impr...

PURPOSE The purpose of this study was to determine the effect of comprehensive dental rehabilitation on the percentile weight and percentile growth velocity of children with early childhood caries (ECC). METHODS The percentile weight categories of children with noncontributory medical histories and ECC were compared to caries free comparison patients, before and after comprehensive dental tre...

BACKGROUND Macrosomia has been defined in various ways by obstetricians and researchers. The purpose of the present study was to search for a definition of macrosomia through an outcome-based approach.

PURPOSE Overweight can be defined by the body mass index (BMI) and is likely associated with an increased cardiovascular disease risk. However, waist circumference (WC), a central adiposity index, may be a better indicator of cardiovascular disease risk. Studies comparing the effects of BMI and WC on cardiovascular risk factors, such as high blood pressure (BP), are rare in adolescents. METHO...

OBJECTIVE To investigate the relationship between the increase of body mass index and the prevalence and severity of asthma in adolescents from Santa Maria, in southern Brazil, and surrounding regions. METHOD A cross-sectional, observational, population-based study was carried out with 4,010 schoolchildren aged 13 and 14 years, without any gender restrictions, who answered the written questio...

Obesity is an established risk factor for non-insulin-dependent diabetes mellitus (NIDDM). Anthropometric measures of overall and central obesity as predictors of NIDDM risk have not been as well studied, especially in women. Among 43,581 women enrolled in the Nurses' Health Study who in 1986 provided waist, hip, and weight information and who were initially free from diabetes and other major c...

Patients with Marfan syndrome (MFS) presents with primary skeletal manifestations such as tall stature, chest wall abnormality, and scoliosis. These primary skeletal manifestations affect the growth pattern in MFS. Therefore, it is not appropriate to use normal growth charts to evaluate the growth status of MFS. We aimed to develop disease-specific growth charts for Korean MFS patients and to u...
