Background: Despite many effort to identify and control the factors involved in
polycystic ovary syndrome (PCOS), there are no available reports indicating the
association of healthy eating index (HEI) and PCOS.
Objective: The present study has been conducted to examine the relationship
between HEI and PCOS.
Materials and Methods: In this case-control study, the study population comprised
297 women aged 20-40 yr referred to Baqiyatallah Hospital Clinics, Tehran, Iran in
two groups: case group (n=99) and control group (n=198). The usual dietary data
were collected using a validated 168-item semi-quantitative food frequency
questionnaire. Standard anthropometric measurements (height, weight, and waist
circumference) were also taken. Unconditional logistic regression was used to
analyze the relationship between the PCOS and the HEI.
Results: The mean age and body mass index of case and control groups were 29±5.5
vs. 29.5±6 yr and 26.6±4.8 vs. 26±4.2 kg/m², respectively (p=0.752, p=0.822). Mean
HEI scores for the case and control groups were found to be 61 and 65, respectively.
In final model and after adjustment for confounders, the prevalence of PCOS in
subjects in the highest tertile HEI score was significantly (50%) less than those in
the lowest tertile HEI score (OR=0.50; 95% CI: 0.25-0.74, p=0.001).
Conclusion: Our results suggest that HEI score is inversely associated with the risk
of PCOS in adult women.
