studied in high income countries, but have been less well researched in
low/middle income countries. This is despite robust theoretical evidence of
environmental transitions in such countries which could result in biological
adaptations that lead to increased hypertension and cardiovascular disease
risk. Data from the Birth to Twenty bone health sub-sample (n= 358, 47%
female) were used to model associations between household socio-economic
status (SES) in infancy, household/neighborhood SES at 16 years, and
systolic blood pressure (multivariate linear regression) and risk for systolic
pre-hypertension (binary logistic regression). Bivariate analyses revealed
household/neighbourhood SES measures that were significantly associated
with increased systolic blood pressure. These significant associations
included improved household sanitation in infancy/16 years, caregiver owning
the house in infancy, and being in a higher tertile (higher SES) of indices
measuring school problems/environment or neighbourhood
services/problems/crime at 16 years of age. Multivariate analyses adjusted for
sex, maternal age, birthweight, parity, smoking, term birth, height/body mass
index at 16 years. In adjusted analyses, only one SES variable remained
significant for females; those in the middle tertile of the crime prevention index
had higher systolic blood pressure (β = 3.52, SE = 1.61) compared to the
highest tertile (i.e. Those with the highest crime prevention). In adjusted
analyses, no SES variables were significantly associated with the systolic
blood pressure of boys, or with the risk of systolic pre-hypertension in either
sex. The lack of association between SES and systolic blood pressure/systolic pre-hypertension at age 16 years is consistent with other studies showing an
equalisation of adolescent health inequalities. Further testing of the
association between SES and systolic blood pressure would be
recommended in adulthood to see whether the lack of association persists.
