The Relationship Between Breast Feeding and Body Mass Index and Blood Pressure in Pre-School Children

Introduction: It is generally accepted that breast feeding has a beneficial effect on the health of infants and children. The evidence that breast feeding protects against obesity is inconclusive also the influence of breast feeding on blood pressure in later life is uncertain. The major aim of this study was to assess the association between method of infant breast feeding and components of the body mass index and blood pressure in pre-school children. Materials & Methods: In a cohort study, a total of ۸۰۰ pre-school children, ۳۵۹ (۴۷.۲%) males, and ۴۰۲ (۵۲.۸%) females, born in ۲۰۰۳ in Yazd, Iran were selected based on a systematic stratified random model. Of eight hundred questionnaires sent, ۷۶۱ (۹۵%) were returned to the investigators. At ۶ years, blood pressure was measured on the right arm at rest. Body mass index (BMI) was calculated by dividing the weight in kilograms by the square of height in meters (kg/m۲).Data on infants feeding were collected respectively during first two years of life .Data were managed and analyzed using SPSS (SPSS, Inc, version ۱۳.۰) Results: Of the ۷۶۱ subjects included in this study, ۴۵۲ (۵۹.۴%) were exclusively breast fed, ۱۳۶ (۱۷.۹%) were bottle fed and ۱۷۳ (۲۲.۷%) were partially breast fed. Body mass index was not significantly different between bottle feeding, partial and exclusive breast feeding groups (P=۰.۳۹۸) ..No relationship was found between method and duration of breast feeding, and systolic blood pressure (P=۰.۲۴۴), diastolic blood pressure (P=۰.۷۸۱) and mean blood pressure (P=۰.۴۸۳). Conclusion: We did not find association between method of infant feeding, duration of breast feeding and systolic, diastolic mean blood pressures and also with body mass index
