Dash diet may help women limit cognitive function decline in later life

There needs to be more data available on the role of mid-life Dietary Approaches to Stop Hypertension (DASH) diet in late-life SCCs. This background was studied in the present study. The study had 5116 women of mean age 46 years from the New York University Women's Health Study, and SCCs were assessed from 2018-2020 by a 6-item questionnaire.

The key results of the study are:

• Compared to women in the bottom quartile of the DASH scores, the odds ratio (OR) for having two or more SCCs was 0.83 for women in the top quartile of DASH scores at baseline.
• The association was similar with multiple imputation and inverse probability weighting to account for potential selection bias.
• Among women without a cancer history, the inverse association was stronger.

They said that greater adherence to the DASH diet in mid-life lowers the prevalence of late-life SCCs in women.

Study strengths include large sample size, diverse study population, the prospective study design, the inclusion of middle-aged women, long-term follow-up and the availability of detailed longitudinal data on lifestyle and comorbidities.
