title: Body size, fat distribution, menarcheal age and blood pressure in 14-year-old girls.
abstract: BACKGROUND
  The relationships between body size and fatness and blood pressure are generally acknowledged. The majority of the few studies that have examined the effect of fat distribution and maturation rate on blood pressure have used secondary sex characteristics as the measure of maturity. The aim of the present study is to examine the associations between blood pressure and relative weight, fat distribution, recalled menarcheal age and occurrence of menstruation (yes/no) in a sample comprising of 1149 14-year-old girls.
  
  
  METHODS
  Systolic and diastolic blood pressure (DBP), height, weight and body circumferences were measured using standard protocols. Fatness was expressed as body mass index (BMI, kg/m2), whereas fat distribution was estimated by using waist-to-hip ratio. The girls' maturity status was assessed from exact recalled date of menarche. One-way analysis of covariance and multiple linear regression analyses were used to determine the strength of association among systolic blood pressure (SBP), DBP and BMI, menarcheal age and indices of fat distribution.
  
  
  CONCLUSIONS
  Height and BMI are significantly associated with SBP. Relative weight is the most important factor related to SBP independently of chronological age and maturity status. Height and age at menarche are significantly associated with DBP. Height of 14-year-old girls shows the same strength of association with SBP and DBP, whereas maturity status negatively correlates with DBP. Fat distribution shows no effect on the level of DBP in girls.
