Controversial results have been reported about the association of calcium, magnesium, and phosphorus and stroke risk, but none in China. To investigate the association between dietary calcium, magnesium, phosphorus, and stroke incidence in Chinese adults, we collected data from the China Health and Nutrition Survey (CHNS) from 2004 to 2011, including 6411 participants aged 45–79 years and free of stroke at baseline. Diet was assessed by interviews combining 3-d 24-h food recalls and household food inventory weighing at each survey round. The stroke incident was identified based on the validated self-report. Multivariate Cox regression models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs). For 32,024 person-years of follow-up, 179 stroke cases were documented. After adjustment for major lifestyle and dietary risk factors, calcium intake was positively associated with reduced stroke risk, and the HR of stroke comparing extreme quartiles was 0.53 (95% CI 0.29–0.96, Pdevelopment = 0.03). In further stratified analyses, significant heterogeneity across sex strata was found (Pcorrespondence = 0.03). Dietary calcium intake among men was more inversely related to stroke, with HRs being 0.33 (95% CI 0.15–0.76, P trend = 0.02), compared to 1.24 (95% CI 0.46–3.35, Ptrend = 0.89) among women. However, no significant association between stroke and magnesium or phosphorus was revealed. Our findings suggest that higher dietary calcium intake was associated with a lower risk of stroke in Chinese adults, particularly in men.
Inclusion
While the a great cerebrovascular problem, stroke has become the best cause of dying in the setup and developing nations. A good 10% full yearly demise all over the world try estimated to be attributable so you’re able to it 1 . Probably the heart attack survivors, as much as fifteen–30% was forever disabled 2 , which results in around 113 billion disability-modified existence decades missing 3 . China gets the high projected lifetime chance of coronary attack all over the world (39.3%) with regards to the 2016 all over the world weight out of situation (GBD) regional study 4 . Appear to, coronary attack is a serious public health issue getting China into the against the elevated ageing populace. Ergo, identifying the newest convertible chance products is actually clicking into reduction and you will the improvement out of lifetime top-notch coronary arrest clients additionally the avoidance out of enormous socio-financial weight.
Dieting calcium, magnesium, and you will phosphorus intakes and you may likelihood of stroke for the Chinese adults
As the direct etiology isn’t totally elucidated, coronary attack can be considered a sickness about genetic and you may environmental exposure situations (particularly diet) or the interplay of them things. Extensive proof shows that weight loss adjustment are beneficial to get rid of the latest onset of stroke 5,six,seven . A close matchmaking can be obtained anywhere between calcium supplements, magnesium, phosphorus, and vascular shelter, which can be believed important wellness implications to have vascular ailment simply because they can be regulate vascular calcification and endothelial dysfunction 8,9 . Up to now, several studies have tested the partnership anywhere between these types of nutrition consumption and you may coronary arrest risk ten,eleven,12 , however the results are inconsistent. Like, browse throughout the Eu populace displayed magnesium consumption, although not calcium supplements is actually notably regarding a diminished danger of coronary attack eleven . Alternatively, in the us, calcium consumption, instead of magnesium, contributes to ong men, magnesium intake are inversely for the coronary arrest 12 . In addition, each one of these studies was used during the west communities with a high consumption of those vitamins thirteen,fourteen . But not, to the knowledge, absolutely nothing known regarding the connection off diet calcium supplements, magnesium, and you can phosphorus intakes having coronary attack chance on Chinese population. The typical weight reduction intake of these micronutrients one of Chinese someone consuming mostly bush-mainly based dieting was reported to be below regarding Europeans and you can Us americans that a whole lot more whole milk and you will beef facts fifteen . Within this context, an enormous-measure prospective study throughout the Chinese society so you’re able to love ru supplement this new association’s proof is actually admittedly requisite. I, hence, utilized analysis regarding China Health insurance and Nutrition Survey (CHNS) to check the relationship anywhere between slimming down calcium supplements, magnesium, and phosphorus consumption and you can after that chance from heart attack for the Chinese adults.
