The Blood Pressure Study in Mexican Children (BPSMC): I. Distribution and correlates of blood pressure in adolescent Mexican girls. International Journal of Epidemiology 1992; 21:40-47.Blood pressure nses in adolescence and its increase appears to be more closely related to body size than to age. This cross-sectional study assessed the relationship between selected anthropometric and demographic factors and blood pressure during early adolescence in a sample of 233 females aged 10-12 years enrolled in public and private primary schools in Tlalpan, Mexico. Standardized measurements of blood pressure, arm circumference and length, height, weight, body mass index, and triceps skinfold were obtained. All anthropometric attributes were strong univariate cor relates of blood pressure. Multiple regression analyses suggest positive associations between both body mass index and arm length and systolic blood pressure early in adolescence. When cross-cultural comparisons were made of blood pressure levels in the Blood Pressure Study in Mexican Children (BPSMC) with results in other countries, the BPSMC mean blood pressure levels were found to be the lowest. Possible explanations are discussed.
