Relación entre circunferencia de cintura y presión arterial en mujeres guatemaltecas: el estudio CRONOS

Fundaments

Several studies have reported an association between blood pressure and central adiposity. The objective of this study was to determine the relationship of waist circumference (WC) and blood pressure (BP) among a group of young (Y) and old (O) women living in Quetzaltenango, Guatemala.

Methods

196 women, 97 between 35–45y (Y), and 99 from 60 to 75y (O), using a multicentric protocol from CRONOS study. Hypertension was defined as systolic blood pressure (SBP) ≥140 mmHg and diastolic blood pressure (DBP) ≥ 90 mmHg.

Results

For the Y and O groups, the percentage of hypertension was 9% and 40%, respectively; 38% of the Y group were overweight, as compared to 45% of the O group. Obesity was 28% in the Y group and 23% in the O group. Mean WC was identical between groups: Y= 82,5 ± 9,7 cm and O= 82,5 ± 9,9 cm; the Pearson and Spearman correlations between WC and SBP or DBP were not significant for the young group (p > 0,05). In the older group, the correlation between WC and DPB was significant in both: Pearson (r = 0,34; p < 0,01) and Spearman (r = 0,35, p < 0,01).

Conclusions

In this particular population with overweight and obesity, the positive association between WC and BP was observed in the older women group, who also has the mayor percentage of hypertension.
