P1697Consistently stable body mass index and atrial fibrillation: national health insurance service-health screening cohort study in Korea

Abstract Background: The number of patients requiring dialysis is increasing worldwide, and the atrial fibrillation (AF) prevalence among hemodialysis (HD) patients is higher than in the general population. There have been no studies of Korean AF patients undergoing HD investigating how AF affects outcomes, for example, in terms of all-cause mortality, hospitalization, and stroke events. We conducted a large-scale retrospective cohort study with data from the National Health Insurance System (NHIS) to determine how AF affects these outcomes. Methods: In 2013, the Health Insurance Review and Assessment (HIRA) service, a Korean national health insurance scheme, collected data from 21,839 HD patients for evaluating the adequacy of dialysis centers. All-cause mortality, hospitalization, and stroke events were compared between patients with and without AF. Sub-analyses compared these outcomes between patients receiving and not receiving warfarin. Results: Cox regression analysis found that AF was a significant risk factor for death from any cause (HR, 1.356; 95% CI, 1.222-1.506, P < 0.001), hospitalization (HR, 1.323; 95% CI, 1.225-1.430, P < 0.001), and hemorrhagic stroke (HR, 1.500; 95% CI, 1.050-2.141, P = 0.026). AF was not significantly associated with an increased risk of ischemic stroke. The use of warfarin was significantly associated with hemorrhagic stroke incidence (HR, 1.593; 95% CI, 1.075-2.360, P = 0.020), while there was no significant correlation between warfarin treatment and all-cause mortality, hospitalization, and ischemic stroke. Conclusions: This cohort study of Korean dialysis patients showed that AF was a risk factor for multiple outcomes among HD patients.

Purpose: The aim of this study was to investigate the intensity of physical activity predicting afterward childbirth for infertile women in order to improve the development of an infertility support.Methods: The complete enumeration data of the National Health Insurance Service of Korea for women who had been diagnosed with infertility in 2016 were analyzed to investigate the predictors of childbirth in 2016–2017. The data were analyzed using descriptive statistics and linear regression with SPSS.Results: When age and body mass index were controlled for, intermediate intense physical activity increased the rate of childbirth, but low or heavy intensity did not.Conclusion: Women who have been diagnosed with infertility should be given advice to engage in intermediate levels of physical activity in order to increase their chances of having a child.

Background: Waist circumference (WC) is an index of abdominal obesity and associated with co-morbidities and mortality. Higher WC is positively associated with increased mortality; therefore, we examined the relationship between WC and mortality in Korean populations with the interaction of body mass index (BMI) and WC for mortality. Methods: A total of 23,263,878 subjects (men = 11,813,850 and women = 11,450,028) who were older than 20 years and underwent the National Health Insurance Service health checkup were included. WC was divided into six categories by 5 cm increments and level 3 (85–90 cm in men and 80–85 cm in women) was referenced. Multivariable Cox proportional hazard models were used to obtain the hazard ratios (HRs) and 95% confidence intervals for all-cause mortality according to the six levels of WC. Results: WC in 5 cm increments showed a positively increased all-cause mortality after adjusting for all covariates including BMI. Men showed higher HRs for mortality than women as WC increased, and the HRs were higher in the lower WC levels, but lower in the higher WC levels among the subjects aged 65–85 years than subjects aged 40–65 years. Even in subjects with normal weight and overweight, increased WC (levels 4, 5, and 6) showed increased HRs for mortality (HRs = 1.156, 1.412, and 1.614 in normal BMI and 1.145, 1.401, and 1.909 in overweight, respectively). Conclusion: There was a linear association between WC and all-cause mortality across all BMI categories even in the subjects with normal or overweight BMI. Physicians should check WC routinely even in the subjects with normal weight or overweight.
