Factors Associated with Halitosis in White-Collar Employees in Shanghai, China.

ABSTRACT:

Objective

To investigate the factors associated with halitosis in Chinese white-collar employees.

Materials and methods

Subjects in three randomly selected office buildings in Shanghai, China, were enrolled in this cross-sectional study using cluster random sampling. Oral malodor was assessed by measuring volatile sulfur compounds (VSCs) with a portable sulfide monitor. Subjects' oral health, including dental caries, periodontal status, and tongue coating, was evaluated clinically. A questionnaire was used to obtain information about participants' demographic characteristics, oral hygiene habits, and health behaviors.

Results

Of the 805 subjects invited to participate in this study, 720 were enrolled (89.4% response rate). Data from these subjects were used for statistical analyses. The prevalence of halitosis was 33.2%. In the final regression model, halitosis was significantly related to tongue coating thickness, periodontal pocket depth, no food consumption within 2 hours prior to oral examination, and less intake frequency of sweet foods.

Conclusions

In this Chinese white-collar population, tongue coating and periodontal disease were associated with halitosis. Oral hygiene education should be provided at the population level to encourage the maintenance of oral health and fresh breath. Consumption of sweet foods may reduce VSC production, although this finding requires further investigation.

Project description:BACKGROUND:This study aims to understand the deciduous dental caries status of preschool children in Xuhui District of Shanghai, China and to analyze the associated risk factors. METHODS:In January of 2016, a cross-sectional investigation was conducted to examine the oral health of all the kindergarten children in Xuihui District of Shanghai, China. Meanwhile, a field questionnaire survey was conducted with the children's guardians to ascertain the potential risk factors associated with deciduous dental caries. RESULTS:Among 11,153 children, the prevalence of deciduous dental caries was 47.02%, and the mean dmft score was 2.21. The first three predilection sites were maxillary central primary incisors, mandible second primary molars, and mandible first primary molars. There were statistically significant differences in caries prevalence and dmft among different age groups and different household registration (Hukou) types (P?<?0.001). Multivariate Logistic regression suggested that the possible risk factors for deciduous caries included: older age, drinking sweetened beverages frequently, often or usually eating sweets before sleep compared to rarely/never eat them at this time, exclusive or predominant breastfeeding compared to exclusive or predominant artificial feeding and latter introduction of toothbrushing. On the other hand, Shanghai Hukou families, high educational level of guardians (high school or college education), regular parental support for children's toothbrushing, guardians' oral health knowledge, and a good perception about children's oral health conditions were shown as potential protective factors for deciduous dental caries. CONCLUSIONS:The deciduous dental caries status of preschool children in Xuhui District of Shanghai was still serious. The caries prevalence in Xuhui, China, is associated with children's age, household registration type, oral health habits, feeding habits, guardians' education level, parental perception about children's oral health and knowledge about oral health.

Project description:BACKGROUND:Vitamin D deficiency is widespread in China, particularly among older adults. Factors associated with suboptimal vitamin D levels are not well defined. The present study was a population-based study that included 10 urban and suburban communities in Shanghai, to evaluate vitamin D status and its correlates among older adults. METHOD:This cross-sectional study was based on study data for 3924 healthy men and women aged 65-95 years. Anthropometric and socioeconomic data were collected in June-July 2014. Serum 25(OH)D levels were detected using a chemiluminescence immunoassay. The following socioeconomic data were obtained through self-administered questionnaires: education level, lifestyle, residency, and dietary habits. A logistic regression model was used to assess associations between anthropometric factors, socioeconomic factors and serum 25(OH)D levels. RESULTS:Median levels of serum 25(OH)D in men and women were 22.73 and 19.99 ng/mL, respectively. Vitamin D deficiency was common in subjects, even though data collection was conducted during summer. The general prevalence of serum 25(OH)D levels <20 ng/mL were 35.4% and 50.5% for men and women respectively. The general prevalence of serum 25(OH)D levels <10 ng/mL were 2.73% and 5.9% for men and women respectively. A multivariable model indicated serum 25(OH)D levels ?20 ng/mL were significantly and positively correlated with male sex, calcium or vitamin D supplementation, and residency in suburban communities. The model also indicated that high level of physical activity was protective factors of vitamin D deficiency for men and milk consumption for women, respectively. By contrast, deficient serum 25(OH)D levels were significantly correlated with education level (lower than primary school) or obesity [body mass index (BMI) ? 26.06 kg/m2] for men or women, respectively. CONCLUSION:This cross-sectional study of older adults in communities in Shanghai demonstrates that key factors positively correlated with serum 25(OH)D levels ?20 ng/mL include male sex, residency in suburban communities, calcium or vitamin D supplementation, high physical activity and education level (for men), and dairy consumption and maintenance of normal BMI (for women).
