Environmental factors associated with pre-term delivery in Jamaica

Social and environmental factors were related to preterm delivery in a national population of 10,330 singleton births occuring in the Jamaican National Perinatal Morbidity and Mortality Survey of 1986. Among women certain of their dates, the preterm delivery rate was 14.2 por ciento . Initial two-way tabulations indicated that the significant associations with preterm delivery were the marital status of the mother, her educational level, the job of the major wage earner, whether she was herself the major wage earner, her usual employment status, the food expenditure per person in the household and the parish in which she resided. In addition, there were associations with tobacco smoking (positive) and alcohol consumption (negative). Mothers who were in work at the time of quickening had a reduced risk of of preterm delivery. There was no association with coital rate at quickening. Mothers who were young or relatively old (35+) also had an increased risk of preterm delivery. Logistic regressiion was used to determine the statistically significant independent associations. These were found to be: parish of residence, maternal age, marital status of the mother, the job of major wage earner in the household, maternal cigarette smoking and the amount spent on food in the household. There were no independent associations with maternal education level or alcohol ingestion.

Maternal mortality in Jamaica: socioeconomic factors

Socioeconomic factors relating to all maternal deaths identified during the 12 months of the Jamaican Perinatal Morbidity and Mortality Survey were compared with a control population of over 10,000 women. The maternal mortality rate was 11.5 per 10,000 livebirths. Initial analyses showed (a) a negative trend in risk of maternal death with increasing maternal education level, (b) that mothers who lived in households with direct pumped water and/or flush toilets enjoyed a reduced risk, (c) mothers who were themselves the major wage earner and (d) those living in households where the major wage earner was a farmer were at increased risk of maternal death. A previous analysis showed that the mothers age, her parity and variables indicating access to medical care were important. Logistic regression showed that only maternal age and toilet facilities were independently associated with maternal mortality.
