Abstract P202: The Impact of Snoring with and without Overweight on the Incidence of Hypertension among Japanese General Population
Introduction: Evidence for the longitudinal impact of snoring on incident hypertension in Asians is still limited. The objective of this study was to examine whether the impact of snoring with and without overweight (body mass index ≥25.0 kg/m2) on the incidence of hypertension among Japanese general population.
Hypothesis: We assessed the hypothesis that the impact of snoring on incident hypertension among Japanese general population was more evident for non-overweight (body mass index <25.0 kg/m2) subjects probably because overweight is a primary determinant of both snoring and hypertension.
Method: A total of 7,482 non-hypertensive persons (2,891 men and 4,591 women) aged 35-79 years from three communities in Japan who participated in the Circulatory Risk in Communities Study (CIRCS) were followed up for 7.9 years. Hazard ratios for the incidence of hypertension were calculated according to snoring (self-administered questionnaire) stratified by body mass index.
Results: At baseline, 74 % of men and 59 % of women had sometimes or everyday snoring and 31 % of men and 28 % of women had being overweight. During the 7.9-year follow-up period, 1087 individuals (451 men and 636 women) developed hypertension. The multivariable-adjusted odds ratio (95%confidence interval) of incident hypertension for snoring compared with non-snoring was 1.37 (1.06 to 1.76) for men and 1.32 (1.10 to 1.58) for women. When stratified by body mass index at baseline, the significant association was observed only in non-overweight; the multivariable adjusted odds ratio of incident hypertension with non-overweight was 1.52 (1.12 to 2.04) for men and 1.39 (1.11 to 1.73) for women, and respective odds ratio for snoring with overweight was 1.11 (0.68 to 1.81) for men and 1.14 (0.83 to 1.53) for women compared with non-snoring categories although the interaction was not statistically significant. The population-attributable fraction (PAF) of snoring with non-overweight for incident hypertension was 26 % for men and 17% for women.
Conclusions: Snoring may have larger impact on development hypertension among non-overweight Japanese men and women.
