Mutans streptococci (mutans) have an important role in dental caries. Individuals having high levels of these organisms being considered to be a higher risk of disease. The aim of this study was to assess the effectiveness of a prenatal nutrition intervention to reduce sugar intake and mutans in low-income women.
Pregnant women ≥18 years of age; with high mutans levels ( > 10 000 colony forming units/ml) were randomized to receive education alone (Control) or education and a 1-hour nutrition group session at 9 months and 6 weeks postpartum (Test). Mutans and questionnaire data were collected at baseline, 9 months, 6 weeks, and 3 months postpartum. Sugar intake was assessed by the Food Frequency Questionnaire and clinical information was abstracted from medical charts.
- 120 completed the baseline visit and 93 (77%) completed all four visits.
- The mean age of the participants was 26.3 years
- 73% were Hispanic, 29% had lived in the United States < 6 years;
- 48% completed high school; 27% were married;
- mean total sugar intake at baseline was 149 g (SD = 85).
- Repeated measures analysis of variance showed that mutans levels declined significantly in both groups, but that the control group had significantly lower mutans levels at the final assessment compared with test group.
- Sugar intake also declined significantly, but there were no significant differences between groups.
The authors concluded
The study demonstrated the following: a) the feasibility of conducting the intervention at community health centre sites among low-income pregnant women; b) the effectiveness of education to reduce mutans/sugar intake; and c) the need to improve the nutrition intervention to obtain additional gains in mutans
