Adherence to Mediterranean Diet Reduces Incident Frailty Risk: Systematic Review and Meta-Analysis.
Journal of the American Geriatrics Society, 2018;
To conduct a systematic review of the literature on prospective cohort studies examining associations between adherence to a Mediterranean diet and incident frailty and to perform a meta-analysis to synthesize the pooled risk estimates.
Systematic review and meta-analysis.
Embase, MEDLINE, CINAHL, PsycINFO, and Cochrane Library were systematically searched on September 14, 2017. We reviewed references of included studies and relevant review papers and performed forward citation tracking for additional studies. Corresponding authors were contacted for additional data necessary for a meta-analysis.
Community-dwelling older adults (mean age ≥60).
Incident frailty risk according to adherence to a Mediterranean diet.
Two reviewers independently screened the title, abstract, and full text to ascertain the eligibility of 125 studies that the systematic search of the literature identified, and four studies were included (5,789 older people with mean follow-up of 3.9 years). Two reviewers extracted data from the studies independently. All four studies provided adjusted odds ratios (ORs) of incident frailty risk according to three Mediterranean diet score (MDS) groups (0–3, 4–5, and 6–9). Greater adherence to a Mediterranean diet was associated with significantly lower incident frailty risk (pooled OR = 0.62, 95% CI = 0.47–0.82, P = .001 for MDS 4–5; pooled OR = 0.44, 95% CI = 0.31–0.64, P < .001 for MDS 6–9) than poorer adherence (MDS 0–3). Neither significant heterogeneity (I2 = 0–16%, P = .30) nor evidence of publication bias was observed.
Greater adherence to a Mediterranean diet is associated with significantly lower risk of incident frailty in community-dwelling older people. Future studies should confirm these findings and evaluate whether adherence to a Mediterranean diet can reduce the risk of frailty, including in non-Mediterranean populations.
Italian who visited USA two times and each time for three weeks in a row. Yes I love your country. As many pointed out the main difficulty in eating as I do at home (fresh fruit once a day and fresh vegetable two times a day) was finding the right options. We managed to do it in San Francisco and NY but it was pretty difficult in Nevada, Utah, Arizona and other remote areas. Let me also point out the HUGE portions. Many time I skipped dinner and split my order with my co traveller. In any case the lack of options of most menu is the main problem. Why having some simple grilled vegetables instead of fries is so difficult? Or a simple green salad with oil/salt/vinegar?
I had to expressly ask for them as out of menu. I also noticed that in more expensive places vegetables were more available. Here in Italy also the cheapest place (except for fast food) have vegetables option for a very low cost.
In any case I want to point out that I asked for these because I was grown up eating many veggies. And this bring back the problem to education and upbringing.
Children eat what they parents eat (not what parents tell them). And of course in Italy is normal to spend a bit of time preparing meals at dinner (vegetables require a lot of time to prepare).
So my guess is if American parents had more time for family maybe they could cook better and healthier.
Just my anecdotal experience.
