Relationship between Intake of Vegetables, Fruit, and Grains and the Prevalence of Tooth Loss in Japanese Women

Abstract

Summary Epidemiological evidence regarding dental status and its relationship to diet and nutritional status has been limited. The present cross-sectional study examined the relationship between intake of vegetables, fruit, grains, antioxidants, and fiber and the prevalence of tooth loss. Study subjects were 1,002 pregnant Japanese women. Tooth loss was defined as the previous extraction of 1 or more teeth. Adjustment was made for age, gestation, parity, cigarette smoking, passive smoking at home and at work, family income, education, changes in diet in the previous 1 mo, season when data were collected, and body mass index. Of the 1,002 subjects, 256 women had lost 1 or more teeth. Compared with intake of vegetables other than green and yellow vegetables in the lowest quartile, consumption of the other vegetables in the highest quartile was independently associated with a decreased prevalence of tooth loss, showing a clear inverse dose-response relationship. There was a marginally significant inverse dose-response relationship between the intake of insoluble fiber and tooth loss. No association was observed between intake of green and yellow vegetables, soluble fiber, or antioxidant nutrients and tooth loss. These findings suggested that consumption of vegetables other than green and yellow vegetables and insoluble fiber may be related to a decreased prevalence of tooth loss among young Japanese women.

The Relationship between dental status, body mass index and nutrient intake

“…A study by Marcenes et al (4) showed a low intake of non-starch polysaccharides, proteins, iron, calcium, niacin and vitamin C in subjects with fewer teeth. A study by Tanaka et al (24) did not reveal any relationship between intake of vegetables, fruits, antioxidants, soluble fibers, vitamin C, vitamin B and beta-carotene on the one hand and the incidence of edentulism in Japanese women on the other hand, in contrast to the results of the present study.…”

Systematic review and meta-analysis of energy and macronutrient intakes during pregnancy in developed countries

“…Demographic and methodological data were extracted for the following confounding factors: stage of gestation, age, ethnicity, socioeconomic status (SES), smoking status, year of sample recruitment, and dietary assessment tool. Three studies reported data from the Osaka Maternal and Child Health Study 30–32 . Data were combined to provide a larger data set of nutrient variables; the data set is referred to as an individual study in analyses.…”

“…Three studies reported data from the Osaka Maternal and Child Health Study. [30][31][32] Data were combined to provide a larger data set of nutrient variables; the data set is referred to as an individual study in analyses. Due to the large number of studies included, original authors were contacted only to confirm the year the study sample was recruited.…”

Cross-cultural validity of a dietary questionnaire for studies of dental caries risk in Japanese

“…A diet history questionnaire, consisting of 110 food items selected mainly from a food list used in National Nutrition Survey of Japan, was developed for use in health education. Tanaka and colleagues used this diet history questionnaire to hypothesize a negative relationship between tooth loss prevalence and the intake of magnesium [8], and also between tooth loss and the insoluble fiber foods [9] among Japanese women. However, the reliability of this instrument was not reported.…”
