Versions Notes
Background: The burden of non-communicable diseases (NCDs) is increasing in low-to middle-income countries (LMIC), increasing disproportionately for women in LMIC compared to women in high income countries. Pacific Island Nations (PIs) have some of the highest rates of NCDs globally, and account for nine of the most obese nations. With the transition from a traditional to a westernised diet, nutritional intake is a key modifiable risk factor. Given the United Nations Sustainable Development Goals of good health and wellbeing and gender equality, understanding sex differences in dietary intake and related health outcomes is needed to tailor interventions.
Methods: A systematic review was conducted in January 2018. Studies included provided information on diet, disaggregated by sex in a general PI population (15–64 yrs). Electronic databases and grey literature were searched. Sex differences in dietary intake were described and differences in diet related NCD risk factors (body mass index (BMI), hypertension, dyslipidaemia and high blood glucose) assessed. Where possible, studies were combined in a meta-analysis to quantify differences.
Results: Of 1529 records found, 22 met the inclusion criteria. These studies included information on energy (n = 6), fat (6), carbohydrate (2), salt (2) and fruit and vegetable (13) consumption. Men had a higher energy intake than women by 264 (95% CI 238, 290) kcal/day. Women consumed fruit and vegetables slightly, but significantly, more frequently than men, by 0.14 (0.23, 0.05) and 0.24 (0.40, 0.08) days/week, respectively. Women had higher BMIs than men in all 13 countries surveyed, by 2.30 (2.97, 1.64) kg/m2, overall. Conversely, systolic blood pressure was higher in men, by 6.93 (4.89, 8.97) mmHg. Remaining risk factors showed no differences.
Conclusions: These findings illustrate sex differences in diet and important differences in BMI and systolic blood pressure in the PIs. There is a need for comprehensive data on diet and hard cardio-metabolic outcomes to explore long-term ramifications.
