Basic, we omitted circumstances clinically determined to have blood circulation pressure on standard mainly because participants was more likely to transform its weight reduction activities just after perceiving risk

Immediately following draining its bladders, the players seated on the side for over 5 minutes. Their blood circulation pressure is counted using a great calibrated mercury sphygmomanometer because of the a trained health nurse pursuing the a standardized techniques. The participants place its best arm inside the an excellent cuff airbag, counted no less than step one minute anywhere between tracks. We discussed blood pressure level people who possess an indicate off SBP ? 140 mmHg, a suggest of DBP ? 90 mmHg, otherwise delivering antihypertensive procedures depending on the assistance to have stopping and dealing with blood circulation pressure into the China (2010) 23 . All forms of diabetes and you can myocardial infarction was defined predicated on care about-statement out-of analysis because of the a health care professional in public areas healthcare facilities over the condition level. The players ought to provide this new certification out of diabetic issues or myocardial infarction. Investigators need certainly to make sure the new patient’s prognosis off evidence and you will inquiry all the questions ‘Keeps a health care provider actually ever offered the diagnosis of diabetic issues?

Possess a doctor previously offered you the prognosis off myocardial infarction? Treatment explore are defined in accordance with the participants’ notice-statement, in which investigators must query the participants the second concerns: ‘Are you presently getting anti-blood pressure levels pills? Did you utilize the dental treatments, treatment out of insulin, Chinese traditional drug, otherwise homemade remedies to alleviate all forms of diabetes? With respect to the advice to your reduction and you will treatment of blood lipids when you look at the Chinese adults (2006), players which found one of your after the requirements: (1) TC ? six. I also considered most other slimming down covariates, such as complete weightloss opportunity, times, whole grain, meat, fruit, create, saturated oily acidic, polyunsaturated greasy acidic, cereal fibre, Na, K, and you will cholesterol levels consumption, just like the surrogates to control possible losing weight confounding.

Statistical research

Brand new collective average intake out-of calcium, magnesium, and phosphorus is actually determined to reduce inside-individual type which means that obtain a knowledgeable guess of your enough time-label intake. Person-numerous years of realize-up each new member was calculated once the period between your time of finishing of one’s baseline survey and end from follow-up (the new time of last head to or even the check out regarding heart attack diagnosis), any came basic. The chance rates are computed because of the breaking up exactly how many circumstances because of the people-years of realize-right up. The fresh multivariate Cox proportional threats habits were used so you’re able to imagine the newest hazard percentages (HR) and 95% count on durations (95% CI) of creating coronary arrest centered on dieting calcium supplements, magnesium, and you will phosphorus consumption making use of the reduced quartile as the resource classification. On the Cox proportional dangers models, the newest p to possess pattern is accomplished by modeling the median out-of the brand new kinds defined by per quartile due to the fact an ongoing changeable.

We first performed statistical interaction tests between dietary intakes of calcium, magnesium, phosphorus, and other baseline characteristics (Table 1). We used the Kolmogorov-Sminov test to test the normality of all variables. We outlined the baseline characteristics of the participants. We used the t-test for the continuous variables with normal distribution to test for differences and trends between groups. The non-parametric test is applied to the continuous variables with non-normal distribution, and the chi-square test is used for the classified variables. Then, we categorize the three-day average intakes of calcium, magnesium, phosphorus into four levels. We constructed three sequential models to estimate the effect of calcium, magnesium, phosphorus intakes on stroke. Model 2 further added baseline sociodemographic and lifestyle factors such as urbanization index, education, household income, smoking status, alcohol intake, physical activity, BMI, hypertension, diabetes, myocardial infarction, and medication use into the multivariable analysis. Model 3 additionally adjusted for dietary factors including energy (kcal/d), whole grain (g/d), red meat (g/d), fruits (g/d), vegetables (g/d), saturated fatty acid (g/d), polyunsaturated fatty acid (g/d), cereal fiber (g/d), Na (mg/d), K (mg/d) and cholesterol (g/d) 24,25,26 . To further analyze which factors would affect the relationship between the exposure and outcome, we conducted stratified analyses by age at baseline (< 60 and ? 60 years), sex (man and woman), smoking (never and ever), drinking (never and ever), BMI (< 24, 24–28 and > pinalove 28 kg/m 2 ), hypertension, diabetes, and Myocardial infarction. The likelihood ratio test was used to assess the interactions of cross-product terms. The proportional hazards assumption for dietary calcium, magnesium, phosphorus Intakes, and other covariates was checked by Schoenfeld’s residuals, and no violation was found (P > 0.05). Besides, we performed sensitivity analyses to verify the robustness of the primary results. Second, we repeated the analysis using the non-adjusted person-time from the date of the first visit to the time of the most recent visit of stroke diagnosis or to the end of follow-up, whichever came first. Third, we included dyslipidemia as a sensitivity analysis, which confirmed the robustness of our findings to some degree. Tests for trends across dietary intake categories were conducted by modeling the median value in each quartile as a continuous variable in each model. All statistical analyses were performed with STATA version 14.0. All P-values were two-sided, and P < 0.05 was considered to statistical significance.
