Dairy products and colorectal cancer in middle eastern and north African countries: a systematic review

Abstract Background This systematic review was conducted to explain the association between dairy products and colorectal cancer (CRC) risk in Middle Eastern and North African countries (MENA). Methods The database consulted were PubMed, Clinical Trials, and Cochrane to extract the relevant studies published till the 31stof December 2016, using inclusion and exclusion criteria according to Prisma Protocol. The characteristics of these studies comprised the consumption of all types of dairy products in relation to CRC risk. Results Seven studies were included in this review. For dairy products overall, no significant association was found. Regarding modern dairy products, included studies found controversial results with OR = 9.88 (95% CI: 3.80–24.65) and ORa = 0.14 (95% CI: 0.02–0.71). A positive association was reported between traditional dairy products and CRC risk, to OR = 18.66 (95% CI: 3.06–113.86) to OR = 24 (95% CI: 1.74–330.82) to ORa = 1.42 (95% CI: 0.62–3.25), ptrend = 0.03. Calcium was inversely associated with the CRC risk with ORa = 0.08 (95% CI: 0.04–0.17). Conclusion This is the first systematic review which illustrated the association between dairy consumption and CRC risk in MENA region. The results were inconsistent and not always homogeneous. Further specified studies may be warranted to address the questions about the association between CRC and dairy products in a specific context of MENA region

Modified Mediterranean diet score adapted to a southern Mediterranean population and its relation to overweight and obesity risk

Objectives: The current study aimed to develop a modified Mediterranean diet (MMD) score adjusted to the southern Mediterranean countries' cultural specificities and to evaluate associations between adherence to this modified score and overweight/obesity risk in Moroccan adults. Design: Population-based cross-sectional study. Setting: Rural and urban areas of the five greatest provinces of Morocco. Participants: In total, 1516 participants were recruited between September 2009 and February 2017. Dietary assessment was obtained using a validated Moroccan FFQ. We constructed a MMD score focusing on twelve components. The MMD score ranged from 0 (no adherence to the traditional southern Mediterranean diet (MD)) to 12 (maximal adherence) and was categorised as low (scores 0-4), moderate (scores 5-7) and high (scores 8-12). Results: Among the whole population, 754 (50·5 %) were women and 738 (49·5 %) were men, and the mean age was about 55·60 ± 13·70. In total, 58 % of participants were moderately active. Regarding educational level, 50·7 % were illiterate. The prevalence of overweight and obesity was 43·3 and 8·6 %, respectively. In multivariate analyses, close adherence to MMD (scores 8-12) was associated with reduced overweight/obesity risk (OR 0·61, 95 % CI 0·44, 0·84). Conclusion: The prevalence of overweight and obesity was very high among Moroccan adults. Adherence to the traditional southern MD may help prevent overweight and obesity. © 2021 Cambridge University Press. All rights reserved
