[BDSP. Notice produite par INIST-CNRS rGEFR0xD. Diffusion soumise à autorisation]. Observationally, breastfeeding is associated with lower blood pressure in Western developed settings, whereas little association exists in developing settings. However, postnatal characteristics (e.g., breast milk substitutes, infection rates, underweight, and pubertal timing) differ between these settings. We examined the association of breastfeeding with blood pressure at ~ 13 years, using multivariable linear regression, in 5,247 term births in 1997 from a population-representative Hong Kong Chinese birth cohort where socioeconomic patterning of breastfeeding differs from that of Western and developing settings but standard of living, social infrastructure, and postnatal characteristics are similar to those of Western settings. Higher education is associated with short-term breastfeeding but recent migration with longer-term breastfeeding. Compared with never breastfeeding, exclusive breastfeeding for>=3 months was not associated with blood pressure (systolic mean difference=0.82 mm Hg, 95% confidence interval (CI) : - 0.46,2.11 and diastolic mean difference=0.49 mm Hg, 95% CI : - 0.22,1.21), nor was partial breastfeeding for any length of time or exclusive breastfeeding for
