Abstract Background. There is a limited research on the association between combined dietary measures and liver cancer risk. We investigated the association between the four diet-quality index (DQI) scores, the Alternative Health Eating Index-2010 (AHEI-2010), Alternate Mediterranean Diet (aMED); Dietary Approaches to Stop Hypertension (DASH) and Heathy Diet Indicator (HDI) with liver cancer risk, using data from the Singapore Chinese Health Study, a prospective cohort of 63,257 Chinese men and women aged 45-74 at enrollment in 1993-1998 with up to 25 years of follow-up. Methods. The Cox proportional hazard regression method was used to estimate hazard ratio (HR) and its 95% confidence interval (CI) of HCC with each DQI after adjustment for multiple potential confounders. The unconditional logistic regression method was used to evaluate the associations between the DQIs and HCC risk among a subset of individuals who tested negative for hepatitis B surface antigen (HBsAg). Results. During an average 17.7 years of follow-up, 561 incident HCC cases were identified. High scores of AHEI-2010, aMED and DASH, representing higher dietary quality, were associated with lower risk of HCC (all Ptrend<0.05). Compared with the lowest quartile, HRs (95% CIs) of HCC risk for the highest quartile of AHEI-2010, aMED and DASH were 0.71 (0.55-0.91), 0.73 (0.54-0.98), and 0.68 (0.52-0.89), respectively. These inverse associations were stronger in men than in women. No significant association between HDI and HCC risk was observed. Among HBsAg-negative individuals, similar inverse associations were observed, and the strongest inverse association was for aMED that reached statistically significance level (HRQ4vsQ1=0.48, 95% CI: 0.24-0.98). Conclusion. Higher scores of AHED, aMED, and DASH were significantly associated with reduced risk of HCC in this Asian population. The findings support the notion that adherence to a healthier diet may lower the risk of HCC, suggesting that dietary modification may be an effective approach for primary prevention of HCC.

To assess whether better cardiovascular health is associated with a lower long-term risk of CVD in women with a history of adverse pregnancy outcomes (APOs). Using data from the UK Biobank prospective cohort, we included 2,263 participants with prior APOs and 107,260 participants without prior APOs. Life's Essential 8 (LE8) score was assessed at baseline. Multivariable-adjusted Cox models were used to estimate the associations between LE8 score and CVD events. Over a median 13.5 years of follow-up, 11,134 incident CVD events were documented. Among women with prior APOs, the incidence of total CVD was significantly lower in the top tertile compared to the bottom tertile, with a HR (95% CI) of 0.43 (0.29, 0.65). A similar trend was observed in women without APOs, with an HR (95% CI) of 0.55 (0.53, 0.58). With respect to the individual CVD outcomes, among women with APOs, only the associations with coronary heart disease, HR (95% CI) for T3 vs T1: 0.30 (0.17, 0.55) and atrial fibrillation, 0.47 (0.24, 0.91), achieved statistical significance. Women with high LE8 score and prior APOs had a similar long-term cardiovascular risk compared to women with high LE8 score and no prior APOs, 0.95 (0.63, 1.44). Among women with a history of APOs, better cardiovascular health as assessed using LE8 was associated with a significantly lower incidence of CVD, particularly coronary heart disease and atrial fibrillation. The excess risk associated with APOs appears to be attenuated among those with a high LE8 score.
Background The influence of overall lifestyle behaviors on diabetic microvascular complications remains unknown. In addition, the potential mediating biomarkers underlying the association is unclear. This study aimed to examine the associations of the combined lifestyle factors with risks of total and individual microvascular complications among patients with type 2 diabetes (T2D) and to explore the potential mediation effects of metabolic biomarkers. Methods and findings This retrospective cohort study included 15,104 patients with T2D free of macro- and microvascular complications at baseline (2006 to 2010) from the UK Biobank. Healthy lifestyle behaviors included noncurrent smoking, recommended waist circumference, regular physical activity, healthy diet, and moderate alcohol drinking. Outcomes were ascertained using electronic health records. Over a median of 8.1 years of follow-up, 1,296 cases of the composite microvascular complications occurred, including 558 diabetic retinopathy, 625 diabetic kidney disease, and 315 diabetic neuropathy, with some patients having 2 or 3 microvascular complications simultaneously. After multivariable adjustment for sociodemographic characteristics, history of hypertension, glycemic control, and medication histories, the hazard ratios (95% confidence intervals (CIs)) for the participants adhering 4 to 5 low-risk lifestyle behaviors versus 0 to 1 were 0.65 (0.46, 0.91) for diabetic retinopathy, 0.43 (0.30, 0.61) for diabetic kidney disease, 0.46 (0.29, 0.74) for diabetic neuropathy, and 0.54 (0.43, 0.68) for the composite outcome (all Ps -trend ≤0.01). Further, the population-attributable fraction (95% CIs) of diabetic microvascular complications for poor adherence to the overall healthy lifestyle (<4 low-risk factors) ranged from 25.3% (10.0%, 39.4%) to 39.0% (17.7%, 56.8%). In addition, albumin, HDL-C, triglycerides, apolipoprotein A, C-reactive protein, and HbA 1c collectively explained 23.20% (12.70%, 38.50%) of the associations between overall lifestyle behaviors and total diabetic microvascular complications. The key limitation of the current analysis was the potential underreporting of microvascular complications because the cases were identified via electronic health records. Conclusions Adherence to overall healthy lifestyle behaviors was associated with a significantly lower risk of microvascular complications in patients with T2D, and the favorable associations were partially mediated through improving biomarkers of glycemic control, systemic inflammation, liver function, and lipid profile.
Little is known about the joint associations of multiple lifestyle risk factors including smoking, low body mass index, physical inactivity, alcohol consumption, and low diet quality with risk of active tuberculosis.We analyzed data from the Singapore Chinese Health Study, a prospective cohort study of 63 257 Chinese adults aged 45-74 years enrolled between 1993 and 1998. Incident cases of active tuberculosis were identified via linkage with the National TB Registry through 31 December 2016. Cox proportional hazards regression models were used to compute hazard ratios (HRs) and 95% confidence intervals (CIs) of tuberculosis risk in relation to the combined scores of lifestyle risk factors.Compared with participants with none of the risk factors, the adjusted HRs (95% CI) of active tuberculosis for participants with 1, 2, 3, 4, and 5 risk factors were 1.24 (1.02-1.51), 1.84 (1.51-2.23), 2.52 (2.03-3.14), 4.07 (3.07-5.41), and 9.04 (5.44-15.02), respectively (Ptrend < .0001). The HR for those with 5 factors was ~1.5 times the product of individual risk estimates from the 5 factors on a multiplicative scale. The stepwise increase in risk of active tuberculosis with increasing number of lifestyle risk factors was significantly stronger in participants with diabetes than their counterparts without diabetes at recruitment (Pinteraction = .01).Multiple lifestyle risk factors were associated with risk of active tuberculosis in a synergistic manner. Our findings highlight the importance of public health programs and interventions targeting these factors simultaneously to reduce the tuberculosis burden among the general population.
Background Although hypertension is an established risk factor for chronic kidney disease, less is known about the relationship of pulse pressure (PP), a measure of arterial stiffness, with chronic kidney disease. We investigated the association of systolic blood pressure (BP), diastolic BP, PP, and mean arterial pressure with the risk of end-stage renal disease (ESRD) in the prospective population-based Singapore Chinese Health Study. Methods and Results We used data from 30 636 participants who had BP measured at ages 46 to 85 years during follow-up I interviews between 1999 and 2004. Information on lifestyle factors was collected at recruitment from 1993 to 1998, and selected factors were updated at follow-up I. We identified 463 ESRD cases over an average 11.3 years of follow-up I by linkage with the nationwide Singapore Renal Registry. Cox proportional hazards regression models were used to assess the relations between different BP indexes and ESRD risk. Each BP index was positively associated with ESRD when studied individually. However, when PP was included as a covariate, systolic and diastolic BP and mean arterial pressure were no longer associated with ESRD. Conversely, PP remained significantly associated with ESRD risk in a dose-dependent manner (
To examine the association of a healthy sleep pattern with the risk of recurrent cardiovascular events among patients with coronary heart disease (CHD).This prospective cohort study included 21 193 individuals with CHD from the UK Biobank. A healthy sleep score was generated based on a combination of chronotype, sleep duration, insomnia, and excessive daytime sleepiness. Cox proportional hazards regression models were applied to estimate the associations between healthy sleep score and recurrent cardiovascular events. During a median of 11.1 years of follow up, we documented 3771 recurrent cardiovascular events, including 1634 heart failure cases and 704 stroke cases. After multivariable adjustment, including lifestyle factors, medical history, and CHD duration, sleep 7-8 h/day, never/rarely insomnia, and no frequent daytime sleepiness were each significantly associated with a 12-22% lower risk of heart failure. In addition, compared with participants who had a healthy sleep score of 0-1, the multivariable-adjusted HR (95% CI) for participants with a healthy sleep score of 4 was 0.86 (0.75, 0.99) for recurrent cardiovascular events, 0.71 (0.57, 0.89) for heart failure, and 0.72 (0.51, 1.03) for stroke.Adherence to a healthy sleep pattern was significantly associated with a lower risk of recurrent cardiovascular events among patients with CHD, especially for heart failure. These findings indicate that healthy sleep behaviours could be beneficial in the prevention of cardiovascular event recurrence.
BACKGROUND Marijuana impairs the brain development and function among adolescents, but little is known about whether marijuana use is associated with subjective cognitive decline (SCD) among adults. OBJECTIVE We investigated the cross-sectional association between marijuana use and SCD in a representative sample of US adults aged 45 years and older. METHODS The study population included 100,685 participants from five cycles of the Behavioral Risk Factor Surveillance System (BRFSS). Participants self-reported their marijuana use in the past month and whether they experienced SCD or SCD-related functional limitations in the past year. Participants were categorized into past-month marijuana non-users and past-month marijuana users. Among users, they were further classified as occasional (<10 days) and frequent users (≥ 10 days). The weighted, multivariable logistic regression models were fitted to examine the association between marijuana use and risk of SCD, adjusting for age, sex, educational level, chronic disease status, and other potential confounders (odds ratios [ORs] with 95% confidence intervals [95% CI]). RESULTS The sample included 94.2% past-month marijuana non-users, 5.83% users, and 3.45% frequent users. Compared with past-month marijuana non-use, past-month marijuana use was significantly associated with higher odds of SCD (OR = 1.71, 95% CI: 1.42, 2.06). The higher frequency was associated with higher odds of having SCD in a dose-response manner (p Trend < 0.001). Similar associations remained for the SCD-related functional limitations. CONCLUSIONS Our findings provide initial evidence that marijuana use may adversely influence SCD among adults aged 45 years and older. Future prospective studies are warranted to confirm these findings. CLINICALTRIAL NA
