We investigate variation in body mass index (BMI) reference and 5-year all-cause mortality using data from 87151 adult Open University students nationwide. Analyses focused on BMI reference bands: “normal” (≥18.5 to <23), “lower normal” (≥18.5 to <20.75), “upper normal” (≥20.75 to <23), and “narrow Western normal” (≥23 to <25). We report hazard ratios (HR) and 95% Confidence Intervals adjusting for covariates. Compared to lower normal, adults aged 35–65 years who were obese (BMI ≥ 30) were twice as likely to die during the follow-up (HR 2.37; 1.01–5.70). For the same group, when using narrow Western normal as the reference, the results were similar (HR 3.02; 1.26–7.22). However, different combinations of BMI exposure and reference band produce quite different results. Older age persons belonging to Asian overweight BMI category (≥23 to <25) were relatively protected from mortality (HR 0.57; 0.34–0.96 and HR 0.49; 0.28–0.84) when assessed using normal (≥18.5 to <23) and upper normal (≥20.75 to <23) as reference bands. Use of different “normal” reference produced varying mortality relationships in a large cohort of Thai adults. Caution is needed when interpreting BMI-mortality data.

AbstractThe influence of body mass or metabolic capacity on the association between alcohol consumption and lower risks of developing chronic kidney disease (CKD) is not fully elucidated. We examined whether the body mass index (BMI) affects the association between drinking alcohol and CKD. We defined CKD as an estimated glomerular filtration rate decline < 60 mL/min/1.73 m2 and/or positive proteinuria (≥ 1+). Participants were 11,175 Japanese individuals aged 40–74 years without baseline CKD who underwent annual health checkups. Daily alcohol consumption at baseline was estimated using a questionnaire, and the participants were categorized as “infrequent (occasionally, rarely or never),” “light (< 20 g/day),” “moderate (20–39 g/day),” and “heavy (≥ 40 g/day).” Over a median 5-year observation period, 936 participants developed CKD. Compared with infrequent drinkers, light drinkers were associated with low CKD risks; adjusted hazard ratios (95% confidence intervals) were 0.81 (0.69–0.95). Stratified by BMI (kg/m2), moderate drinkers in the low (< 18.5), normal (18.5–24.9), and high (≥ 25.0) BMI groups had adjusted hazard ratios (95% confidence intervals) of 3.44 (1.60–7.42), 0.75 (0.58–0.98), and 0.63 (0.39–1.04), respectively. Taken together, the association between alcohol consumption and CKD incidence was not the same in all the individuals, and individual tolerance must be considered.

Abstract BackgroundThe relationship between body mass index (BMI) and mortality in hypertension patients remains controversial. This study aimed to evaluate the association and the time-varying effects of different BMI categories on the risk of all-cause mortality in hypertension patients. MethodsThis retrospective cohort study was conducted among 212,394 Chinese people with hypertension. All deaths were identified based on Shanghai Vital Statistics. Cox model combined with time-by-covariate interactions was used to estimate the association and the time-varying effects of BMI on the risk of all-cause mortality. The potential non-linear effects across follow-up period for BMI were examined by the application of restricted cubic spline (RCS).ResultsOverall, 31,130 deaths occurred (14.7%) within an average follow-up of 8.24 years. Underweight (<18.5 kg/m2) showed a progressively weakening negative effect on all-cause mortality over time. For both sexes, overweight (23.0-24.9 kg/m2) and class I obesity (25.0-29.9 kg/m2) showed protective effects within 5 years after registration, but these became insignificant in later years. There was no significant difference in the effect on all-cause mortality between class II obesity (≥30.0 kg/m2) and normal weight. in the elderly patients, overweight, class I obesity and class II obesity had continuous protective effects on mortality.ConclusionsAlthough the effect of baseline body mass index on the risk of all-cause mortality varied at different follow-up periods, underweight persistently remained a risk factor for all-cause mortality in hypertension, whereas overweight and class I obesity had protective effects. Thus, in the long-term management of hypertension, more attention should be given to underweight patients.

Gains And Losses

Background: Short-term weight gains and losses are associated with a lower and higher mortality risk, respectively, in patients undergoing hemodialysis (HD). However, little is known about their association with the risk of subsequent hospitalization. Methods: In a prospective cohort of 1,804 HD patients aged ≥65 years enrolled in the Japanese Dialysis Outcomes and Practice Patterns Study phases 3 (2005–2008) and 4 (2009–2011), we examined the associations between changes in body mass index (BMI) over a 4-month baseline period (<–3%, –3 to <–1%, –1 to <1% [reference], 1 to <3%, and ≥3%) and subsequent risk of all-cause, cardiovascular, and noncardiovascular hospitalization using Cox models with adjustment for potential confounders. Results: During a median follow-up of 1.2 years, we noted 1,028 incident hospitalizations for any cause, including 275 and 753 hospitalizations for cardiovascular and noncardiovascular causes, respectively. An L-shaped association was observed between BMI change and all-cause hospitalization. The multivariable-adjusted hazard ratios (HRs; 95% CI) of all-cause hospitalization associated with BMI changes of <–3%, –3 to <–1%, 1 to <3%, and ≥3% (vs. –1 to <1%) were 1.29 (1.01–1.65), 1.22 (0.98–1.51), 1.04 (0.83–1.29), and 1.10 (0.83–1.45), respectively. Qualitatively similar associations were present for cardiovascular-related hospitalization (corresponding HRs [95% CI]: 1.58 [1.06–2.37], 1.09 [0.75–1.58], 0.99 [0.72–1.36], and 0.91 [0.51–1.64], respectively) but not for noncardiovascular-related hospitalization (corresponding HRs [95% CI]: 1.19 [0.90–1.57], 1.26 [0.99–1.59], 1.06 [0.84–1.35], and 1.18 [0.86–1.63], respectively). Conclusions: Decreases in BMI over a relatively short-term period were independently associated with higher risk of subsequent hospitalization, particularly cardiovascular-related hospitalization, among elderly HD patients.

Purpose To determine prospectively whether body-mass index (BMI) is associated with liver-related morbidity and mortality among male hepatitis B virus (HBV) carriers. Patients and Methods We performed a prospective study of 2,903 male HBV surface antigen–positive government employees who were free of cancer at enrollment between 1989 and 1992. Main outcome measures included ultrasonography, biochemical tests, incident hepatocellular carcinoma (HCC), and liver-related death. Results During mean follow-up of 14.7 years, 134 developed HCC and 92 died as a result of liver-related causes. In Cox proportional hazards models adjusting for age, number of visits, diabetes, and use of alcohol and tobacco, the hazard ratios for incident HCC were 1.48 (95% CI, 1.04 to 2.12) in overweight men (BMI between 25.0 and 29.9 kg/m2) and 1.96 (95% CI, 0.72 to 5.38) in obese men (BMI ≥ 30.0 kg/m2), compared with normal-weight men (BMI between 18.5 and 24.9 kg/m2). Liver-related mortality had adjusted hazard ratios of 1.74 (95% CI, 1.15 to 2.65) in overweight men and 1.50 (95% CI, 0.36 to 6.19) in obese men. Excess BMI was also associated with the occurrence of fatty liver and cirrhosis detected by ultrasonography, as well as elevated ALT and γ-glutamyltransferase (GGT) activity during follow-up. The association of BMI with GGT was stronger than with ALT, and elevated GGT activity and cirrhosis were the strongest predictors for incident HCC and liver-related death. Conclusion This longitudinal cohort study indicates that excess body weight is involved in the transition from healthy HBV carrier state to HCC and liver-related death among men.

Abstract Background Obesity has been shown to be related to an increased risk for incidence and progression of atrial fibrillation (AF). Meanwhile, the inverse association between body mass index (BMI) and mortality, so-called “obesity paradox”, is well-known among patients with AF, as well as other cardiovascular diseases. However, data regarding the relationship between BMI and specific causes of death in AF patients remain scarce. Methods The Fushimi AF Registry is a community-based prospective survey of AF patients in Fushimi-ku, Kyoto. The inclusion criterion for the registry is the documentation of AF at 12-lead electrocardiogram or Holter monitoring at any time. We started to enroll patients from March 2011, and baseline characteristics including BMI and follow-up data were available for 3,805 patients by the end of November 2018. Patients were categorized into 3 groups depending on the BMI value; underweight (<18.5 kg/m2; 419 patients), normal (18.5 to <25.0 kg/m2; 2,283 patients), overweight (≤25.0 kg/m2; 1,103 patients). Results In the entire population, the mean BMI level was 23.1±4.0 kg/m2. The lower BMI was associated with higher age (78.5±10.3, 74.0±10.3, and 71.3±10.9 years in Underweight, Normal, and Overweight, respectively; p<0.001) and with higher prevalence of various comorbidities and CHA2DS2-VASc scores (3.83±1.67, 3.43±1.70, and 3.29±1.64, p<0.001). Oral anticoagulants were less frequently prescribed in those with lower BMI (46%, 56%, and 58%, p<0.001). During a median follow-up of 1,464 days (interquartile range: 727–2,228 days), all-cause mortality was lower in accordance with higher BMI (14.3, 5.3, and 3.5 per 100 person-years, respectively; p<0.001). The proportion of infection as a cause of death was prominently higher in the Underweight group than the others (25.7%, 16.7%, and 13.4%, p<0.001) (Figure A). Furthermore, the mortality due to infection was consistently higher in Underweight than in the others in any of the age subgroups (Figure B). Cox models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) of the BMI value for mortality, adjusted by age, sex, chronic kidney disease, anemia, chronic obstructive pulmonary disease, history of major bleeding, and other components of CHA2DS2-VASc score. Higher BMI was related to lower all-cause mortality (per 5 kg/m2 increase: HR 0.71 [95% CIs 0.63–0.78], p<0.001), and also lower mortality due to infection (per 5 kg/m2 increase: HR 0.48 [95% CIs 0.37–0.61], p<0.001). Figure 1 Conclusions In a Japanese community-based AF cohort, obesity paradox was also observed on all-cause mortality. In particular, lower BMI was strongly associated with the mortality due to infection regardless of age.
