Prevalence of overweight and obesity and associated factors among women of childbearing age in Brazil.

OBJECTIVE: To assess the factors associated with overweight and obesity among women of childbearing age in Brazil. DESIGN: Cross-sectional study. SETTING: Using the National Health Survey (PNS) database, from the year 2013. The socio-economic and demographic factors analysed were age, race/skin colour, region, marital status, education level, employment and family income. Concerning health history, diagnoses of hypertension, diabetes mellitus, high cholesterol, heart attack, stroke, chronic kidney disease, menarche, parity and depression were evaluated. For lifestyle information, health status, alcoholic beverage consumption, smoking and physical activity were included. The outcomes were obesity and overweight. The association of excess weight with socio-economic and demographic factors, health history and lifestyle characteristics was investigated according to the appropriate theoretical-conceptual model for the topic. PARTICIPANTS: The sample size was 17 109 women aged 18-49 years. RESULTS: The prevalence of women with excess weight was 55·20 %, with 33·26 % being overweight and 21·94 % with obesity. The factors associated with excess weight were age, non-white skin colour, having a partner, family income of up to two minimum wages, menarche before the age of 12, multiparity, diabetes mellitus, depression, hypertension, high cholesterol, stroke and heart attack. CONCLUSION: The results showed an association between excess weight and socio-demographic factors, both determinants of general and reproductive health history. Implementation of effective public health policies is necessary to prevent unfavourable outcomes related to the health of women of childbearing age with excess weight.

Indexes to assess feeding practices of children under 2 years old: a systematic review.

OBJECTIVE: To systematically review studies that used indexes to assess feeding practices of children under 2 years. DESIGN: Seven databases were searched with no limit on language or publication date. SETTING: The reviewed studies included thirteen Asian, ten Latin American, four European, four North American, three Oceanian and three African. PARTICIPANTS: Children under 2 years. RESULTS: We analysed thirty-six studies: twenty-two presenting original indexes and fourteen using adapted indexes. Among the original indexes, thirteen assess breast-feeding, fourteen food consumption, ten food groups, and ten other feeding practices. Original indexes were mainly adapted to fit the data available in the study, to update for current nutritional recommendations or to add components not present in the original indexes. Seven studies evaluated the associations between the indexes and nutrient intake or nutritional status. The main limitations cited by the authors were: flaws in the definition of the index components, criteria for cut-off points and weighting of the evaluated index components. CONCLUSIONS: The assessment of feeding practices for young children and its comparison across countries remains a challenge, especially due to the lack of consensus on the construction of indexes and regional differences in dietary recommendations and practices. Lack of validation for some indexes also makes it difficult to choose the most appropriate index for a given objective. Adapting existing indexes is a viable option. We point out relevant recommendations that may contribute to future research. Validation and longitudinal studies in diverse populations are favourable to qualify the assessment of feeding practices in this group.

Moderate and severe periodontitis are positively associated with metabolic syndrome.

OBJECTIVE: This study investigated the association between periodontitis severity (exposure) and metabolic syndrome (MetS - outcome), using two criteria for diagnosis of the outcome, since this relationship remains unexplored. MATERIALS AND METHODS: A case-control study was conducted with 870 individuals: 408 with first MetS diagnosis (cases) and 462 without MetS (controls). Participants' general information was obtained using a questionnaire and laboratory data was collected from medical records. Periodontitis severity criteria followed the Center for Disease Control and Prevention: none, mild, moderate, and severe. Odds ratios (OR) and 95% confidence intervals (95% CI) were determined by logistic regression analysis. RESULTS: Findings showed a positive association between moderate and severe periodontitis and MetS: ORadjusted = 1.64 (95% CI: 1.01 to 2.68) and ORadjusted = 1.94 (95% CI: 1.19 to 3.16), respectively, after adjustment for age, sex, schooling level, smoking habit, and cardiovascular disease. The adjusted measurements showed that among individuals with moderate or severe periodontitis, the probability of having MetS was around two times greater than among those without periodontitis, and that the chance was greater among participants with severe periodontitis than those with moderate periodontitis. CONCLUSION: An association between the severity of periodontal status and MetS was found, suggesting a possible relationship between the two diseases. CLINICAL RELEVANCE: MetS influences the etiology of cardiovascular diseases, one of the leading causes of mortality worldwide. The findings suggest that the greater the severity of periodontitis, the greater is the association magnitude with MetS. The health professional needs to recognize that the importance of periodontal disease may play in MetS.

Common mental disorder is associated with periodontitis.

OBJECTIVES: This research evaluated the association between exposure to common mental disorder (CMD) and the presence of periodontitis. BACKGROUND: Common mental disorder is characterized by the presence of irritation, fatigue, insomnia, forgetfulness, decreased ability to concentrate, anxiety, and depression. It has been associated with several diseases; however, there are few studies that have associated it with periodontitis. METHODS: This cross-sectional study was carried out with 621 individuals. Data collection involved the application of a general questionnaire and the self-reporting questionnaire for diagnosis of CMD. The diagnosis of periodontitis involved a full mouth periodontal examination using: clinical attachment level, probing depth, and bleeding on probing. Prevalence ratios and 95% confidence intervals between CMD (exposure) and periodontitis (outcome) were obtained. RESULTS: In the final sample, 38.16% (237) of the individuals were classified with CMD. Among these, 28.27% (67) had periodontitis. Association measurements showed that the occurrence of periodontitis among those exposed to CMD is approximately 50% higher than in those without this mental condition, with statistical significance, after adjustment for age, sex, family income, current smoking habit, alcohol beverage consumption, and cardiovascular disease (PRadjusted  = 1.54, 95% CI: [1.13 to 2.10]). CONCLUSIONS: The findings showed a positive association between exposure to CMD and periodontitis, revealing the importance of broadening public actions targeting mental health, which seems to be related to oral health, mainly due to the high frequency of the diseases in the studied sample.

Is there association between stress and periodontitis?

OBJECTIVE: This study estimated the association between stress and periodontitis. MATERIALS AND METHODS: A cross-sectional study was conducted with a sample of 621 individuals. Information about individuals was obtained through a questionnaire. Stress was evaluated using the Perceived Stress Scale. The diagnosis of periodontitis was based on a complete periodontal examination including clinical attachment level, probing depth, and bleeding on probing. Prevalence ratios (PR), crude and adjusted, and their respective 95% confidence intervals (95%CI) were estimated by Poisson regression analysis. RESULTS: In the final sample, 48.47% (301) of the individuals were classified as having stress, of which, 23.92% (72) had the diagnosis of periodontitis. Association measurements between stress and probing depth ≥ 4 mm (PRadjusted = 1.28, 95%CI [1.04 to 1.58]), stress and clinical attachment level ≥ 5 mm (PRadjusted = 1.15, 95%CI [1.01 to 1.31]), and stress and periodontitis (PRadjusted = 1.36, 95%CI [1.01 to 1.83]) showed that the frequency of these outcomes among those exposed to stress was 15-36% higher than those without the condition of stress, after adjustment for age, sex, schooling level, current smoking habit, pulmonary disease, and body mass index. CONCLUSIONS: The findings showed positive association between exposure to stress and the presence of periodontitis, reaffirming the need to prevent and control stress. CLINICAL RELEVANCE: Although there are limitations in this study, the results showed that an association exists between stress and periodontitis, signaling the necessity of a multidisciplinary attention when considering the psychological status in the management of oral and general health conditions of the individual.

Effect of osteoporosis on periodontal therapy among post-menopausal women.

OBJECTIVE: This intervention study aimed to investigate the effect of osteoporosis on periodontal condition among 48 post-menopausal women undergoing periodontal therapy. MATERIAL AND METHODS: The experimental group, which underwent non-surgical periodontal therapy, was composed of 16 women with periodontitis to be treated, and the control group was formed by 32 women without periodontitis. Oral condition was assessed on three occasions: at the start of the treatment (first examination), 1 month (first re-examination) and 4 months after the end of the therapy (second re-examination). In the second re-examination, recurrence of periodontal disease was evaluated by comparing the clinical measurements obtained pre- and post-treatment. The diagnosis of osteoporosis was made by investigating densitometry reports obtained previously. Descriptive analysis, analysis of variance and the Bonferroni post hoc test were applied to the data gathered, with statistical significance level of 5%. RESULTS: The frequency of periodontitis was 50% in the treated group and 25% in the group without periodontitis. In both groups, this recurrence was greater in subjects with osteoporosis (37.5 and 18.75%, respectively) than in the individuals without osteoporosis (12.5 and 6.25%, respectively). CONCLUSIONS: The preliminary results indicate that osteoporosis possibly has an influence on periodontal condition among individuals undergoing non-surgical periodontal treatment.

Periodontal status as predictor of prematurity and low birth weight.

OBJECTIVE: The objective was to verify the relation between periodontal status and prematurity/low birth weight. METHODS: a case control study of 211 women, 44 being mothers of children born with weight below 2.500g or gestational age of less than 37 weeks (case group) and 177 mothers of children born with weight of over 2.500g or more and gestational age of 37 weeks or more (control group). The women were invited to reply to a questionnaire during the interview. A single dentist performed a complete periodontal exam in the oral cavity of each participant, including: probing depth, recession, plaque index, bleeding on probing, and clinical attachment loss measurements. Descriptive analysis of the study variables was performed and the statistical significance was calculated at 5%, using the chi-squared test. RESULTS: There was no statistically significant difference in the clinical parameters between the groups. CONCLUSIONS: The findings showed no association between periodontal status and prematurity/low birth weight.
