Dietary fruits and vegetables and risk of cardiovascular diseases in elderly Chinese.

ABSTRACT:

Background

Evidence regarding the potential effect of fruit and vegetable consumption on cardiovascular diseases (CVD) was limited and inconsistent among Asian people.

Methods

We prospectively examined associations of fruit and vegetable consumption with the risk of CVD among 9740 participants aged 65 years and older (mean baseline age: 88 years) in the Chinese Longitudinal Healthy Longevity Survey (CLHLS) (2008-2018). Dietary data were collected using a validated food frequency questionnaire.

Results

During 37 366 person-years of follow-up, a total of 3738 CVD cases were recorded. After adjusting for demographics, dietary, lifestyle and economical social factors, higher intakes of total fruits and vegetables were associated with lower risk of CVD [comparing with extreme quintiles, hazard ratio and 95% confidence interval: 0.84 (0.74, 0.95)]. The inverse association was mainly driven by vegetable consumption [0.86 (0.77, 0.95)]. Furthermore, the inverse association was stronger for the risk of hypertension [0.84 (0.72, 0.98)]. These associations were consistent across age, sex, body mass index, residence, exercise status, smoking, drinking, meat intake, modified hPDI and health status.

Conclusions

This study suggests higher intakes of total fruits and vegetables are associated with a lower risk of CVD among elderly Chinese people, supporting the current recommendations of increasing fruit and vegetable consumption as part of a healthy diet for the prevention of CVD.

Project description:PurposeDietary intake and patients' quality of life (QoL) are important supportive care issues in breast cancer survivorship. This study aimed to identify dietary pattern before and after breast cancer diagnosis. In addition, the association between dietary patterns and QoL were cross-sectionally and longitudinally investigated.MethodsA breast cancer cohort which included 1462 Chinese women were longitudinally interviewed at four time-points, namely baseline, 18-, 36-, and 60 months after diagnosis. At each follow-up, validated food frequency questionnaires (FFQ) were used to assess patients' dietary intake, and factor analysis was used to derive dietary patterns. European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30) were used to measure QoL at each follow-up. This study included 1368, 1226, 1079 and 1095 patients with invasive disease who completed assessment at baseline, 18-, 36- and 60-month follow-up and had detailed data of dietary intake and QoL.ResultsBased on data obtained at 18-month follow-up, two major dietary patterns were identified: "grain and animal food pattern" and "vegetables and fruits pattern". Similar dietary patterns were obtained at baseline, 36- and 60- month follow-up. Generalized Estimating Equations (GEE) were used to analyze the longitudinal associations between dietary patterns and QoL over the four follow-ups. High intake of grain and animal food was inversely associated with scores for role functioning (B = - 0.744; 95%CI - 0.147 to - 0.017), dyspnea (B = - 0.092; 95%CI - 0.092 to - 0.092) and constipation (B = - 1.355; 95%CI - 2.174 to - 0.536). Vegetables and fruits intake were positively associated with scores for global health status/QoL (B = 1.282; 95%CI 0.545-2.019), physical functioning (B = 0.545; 95%CI: 0.037-1.053), emotional functioning (B = 1.426; 95%CI 0.653-2.200) and cognitive functioning (B = 0.822; 95%CI 0.007-1.637), while inversely associated with scores for nausea and vomiting (B = - 0.382; 95%CI - 0.694 to - 0.071), dyspnea (B = - 0.570; 95%CI - 0.570 to - 0.570), insomnia (B = - 1.412; 95%CI - 2.647 to - 0.177), loss of appetite (B = - 0.722; 95%CI - 1.311 to - 0.132), constipation (B = - 2.028; 95%CI - 2.775 to - 1.281) and diarrhea (B = - 0.929; 95%CI - 1.481 to - 0.377).ConclusionThis study suggested that high adherence to "grain and animal food pattern" or "vegetables and fruits pattern" was significantly associated with several aspects of QoL. For instance, vegetables and fruits pattern appears to have beneficial effect on global health status/QoL among Chinese breast cancer patients. Prospective follow-up data could further confirm whether a specific dietary pattern has impact on cancer outcomes.

Project description:The atherogenic index of plasma (AIP), a novel composite lipid index, is closely linked to cardiovascular disease (CVD). However, lipid levels fluctuate dynamically, and it is unclear whether there are differences in the association of single-timescale, multiple-timescale, or AIP change trajectories with new-onset cardiovascular disease. Hence, the aim of this study was to investigate the correlation between different AIP parameters and the occurrence of CVD. Data were derived from the China Health and Retirement Longitudinal Study (CHARLS) conducted in 2011, 2015, 2018, and 2020, focusing on middle-aged and elderly populations aged over 45 years. Changes in AIP were classified into three groups using K-means cluster analysis: the low-level growth group (Class 1), the medium-level growth group (Class 2), and the high-level decline group (Class 3). Furthermore, participants were grouped based on tertiles (T) of cumulative AIP (Cum-AIP). Our multivariate logistic regression model integrated adjustments for potential confounders in order to investigate the association between Cum-AIP and the occurrence of CVD. Additionally, we employed restricted cubic spline (RCS) modeling to illustrate the dose-response relationship of baseline AIP, mean AIP, and Cum-AIP with CVD risk. During the 5-year follow-up period, 927 participants experienced the onset of CVD. After controlling for various potential confounding factors, it was observed that individuals in Class 2 demonstrated a notably heightened risk of CVD (OR = 1.23, 95% CI: 1.03, 1.46) and stroke (OR = 1.35, 95% CI: 1.02, 1.80) in comparison to those in Class 1. However, there was no significant difference in the risk of heart disease (OR = 1.21, 95% CI: 0.99, 1.48). In contrast, a noteworthy correlation was solely observed in the Class 3 group concerning the risk of stroke occurrence (OR = 1.60, 95% CI: 1.06, 2.42). The adjusted OR (95% CI) for CVD in the T2 and T3 groups were 1.21 (1.00, 1.46) and 1.30 (1.05, 1.62), respectively, compared to the T1 Cum-AIP group (P for trend = 0.017). Through the RCS model, we identified a positive and linear relationship between baseline AIP, mean AIP, and Cum-AIP with the incidence of CVD. However, the association between baseline AIP and CVD was weak. Sustained elevation of AIP is linked to a heightened risk of CVD in the general population. The elevated mean, and Cum-AIP levels are associated with a heightened risk of CVD. These findings indicate that AIP can serve as a valuable indicator of dyslipidemia, and continuous monitoring and early intervention targeting AIP may contribute to a further reduction in the incidence of CVD.
