Higher calcium intake linked to reduced colorectal cancer risk

Greater calcium consumption is related to diminished colorectal most cancers (CRC) threat throughout tumor websites and calcium sources, in line with a research revealed on-line Feb. 17 in JAMA Community Open.

Semi Zouiouich, Ph.D., M.P.H., from the Nationwide Most cancers Institute in Bethesda, Maryland, and colleagues examined the affiliation between calcium consumption and CRC threat in a cohort research analyzing information from the Nationwide Institutes of Well being-AARP Weight loss program and Well being Research involving members aged 50 to 71 years at baseline (October 1995 to Could 1996) with self-reported good well being and neither extraordinarily excessive nor low caloric or calcium consumption.

The researchers recognized 10,618 first major CRC instances throughout 7,339,055 person-years of follow-up amongst 471,396 members who have been cancer-free at baseline. Imply whole calcium consumption for the bottom quintile (Q1) was 401 mg/d for ladies and 407 mg/d for males; imply whole consumption for the very best quintile (Q5) was 2,056 mg/d for ladies and 1,773 mg/d for males.

A decrease threat for CRC was seen in affiliation with increased whole calcium consumption (Q5 versus Q1: hazard ratio, 0.71; 95% confidence interval, 0.65 to 0.78; P <�  0.001 for development); outcomes have been constant throughout calcium sources and tumor websites. The imply calcium consumption was 382 and 1,916 mg/d for Q1 and Q5, respectively, amongst non-Hispanic Black members, with no affiliation seen for whole calcium consumption with CRC threat (Q5 versus Q1: HR, 0.60; 95% confidence interval, 0.32 to 1.13; P = 0.12 for development). No proof of impact measure distinction was seen by race and ethnicity.

“Whereas calcium consumption might differ by race and ethnicity, the potential for calcium to play a task in CRC prevention seemed to be constant throughout racial and ethnic teams; nonetheless, analysis in racial and ethnic minority populations is required,” the authors write.
