Title: Household diet quality in relation to mortality in Portuguese regions: an ecological study
Issue Date: 2008
Abstract: The aim of this study was to investigate theassociation between regional household diet quality andcorresponding mortality data. Two household diet qualityscores derived from household budget survey food andnutrient data were used: the Mediterranean Adequacy Index(MAI), assessing adherence to a Mediterranean food pattern,and a revised Healthy Diet Indicator (HDIr), based oncompliance with WHO population dietary goals. SevenPortuguese regions were considered, in accordance with theofficially adopted national territorial division NUT II. Thecorresponding regional age-standardised death rates werecalculated for selected diet-related mortality causes. In orderto allow for a minimum of 10 years latency period betweenexposure and outcome, dietary scores from 1989/1990 andits components were correlated to the 3-year average 1999/2001 death rates. Tobacco expenses were included foradjustment. Significant negative correlations with the proportionof families with highest MAI (≥4) or HDIr (≥7)scores were observed for mortality from diabetes mellitus(−0.87, P<0.05; −0.89, P<0.5), cardiovascular diseases(−0.89, P<0.05; −0.96, P<0.01) and ischaemic heartdisease (−0.89, P<0.05; −0.90, P<0.05). Malignantneoplasms were positively correlated with protein, cholesteroland soft drinks, but inversely with polyunsaturatedfatty acids (PUFA). Diabetes showed significant positive correlations with simple sugars and animal fat intake, butinversely with fruits and vegetables. Cardiovascular diseasespresented positive correlations with simple sugars,milk and dairy products and animal fat, but inverse withfruits and vegetables and vegetable oils. Despite thelimitations of ecological approaches in general and of thestatistical power in this particular study, due to the use ofbroad geographical areas, significant correlations in theexpected direction of reduced mortality risk with improvedhousehold diet quality was reported. The use of diet qualityscores in data from household budget surveys could depictvariations in Portuguese regional food and nutrientpatterns, which were revealed to be related and partiallyexplain differences in regional cause-specific mortalityrates from diet-related diseases.
