Private health care provision is important in most middle-income countries but factors influencing the demand for private care have not been well defined. This paper evaluated the relationships of health status and socio-economic variables with utilisation of private care by public primary care clinic attenders. The sample included 2117 randomly selected subjects with clinical diabetes attending 35 government health centres in Trinidad and Tobago. Measures included attendance at a private doctor, the type 2 Diabetes Symptom Checklist, the SF36 questionnaire, and indicators of socio-economic status. Of the sample, 1256 (59%) reported attending a private doctor, 577 (27%) attended a private doctor for diabetes, and 378 (18%) attended a private doctor regularly. Attendance at a private doctor was associated with lower SF36 scores. The odds ratio for a 10 unit increase in SF36 physical component score was 0.81,95% confidence interval 0.72-0.91. After adjusting for demographic and social factors the relative odds were 0.89,0.80 to 1.00. After allowing for differences in health status, the relative odds of attending for private care for those without a pipe borne water supply in the home, compared with those with water in the home, were 0.77,0.63-0.94. Those living alone were less likely to attend a private doctor than those living with their children and partner (odds ratio 0.60,0.43-0.83). Among people attending public clinics, the decision to utilise private care is sensitive to health status. After adjusting for health status there was evidence for horizontal inequity in access to private care in relation to household amenities and composition.
