Direct and indirect associations of experience of racial discrimination, dietary patterns and obesity in adults from southern Brazil.

OBJECTIVE: To analyse the direct and indirect associations of experience of racial discrimination on dietary patterns (DP), obesity and abdominal obesity. DESIGN: This is a cross-sectional population-based study. The main exposure was self-reported experiences of racial discrimination (Experiences of Discrimination scale). The mediator variables were the DP: healthy, Brazilian traditional, sugar and carbohydrates, and fast food. The outcomes were obesity (BMI ≥ 30 kg/m2) and abdominal obesity (waist circumference ≥ 88 cm for women; ≥ 102 cm for men). Structural equation modelling was applied. SETTING: Porto Alegre, Brazil. PARTICIPANTS: Totally, 400 adults aged between 20 and 70 years were participated. RESULTS: The mean age of participants was 47·2 years (sd = 13·9), and 75 % were women. Experiencing racial discrimination had a positive direct effect on obesity (healthy DP: ß = 0·153, P < 0·05; Brazilian DP: ß = 0·156, P < 0·05; sugar and carbohydrates DP: ß = 0·156, P < 0·05; and fast-food DP: ß = 0·153, P < 0·05) and abdominal obesity (healthy DP: ß = 0·206, P < 0·01; Brazilian DP: ß = 0·210, P < 0·01; sugar and carbohydrates DP: ß = 0·204, P < 0·01; and fast-food DP: ß = 0·204, P < 0·01). The experience of racial discrimination did not have a direct effect on DP, nor did it exert an indirect effect on obesity and abdominal obesity through any DP. CONCLUSIONS: A higher experience of racial discrimination is associated with obesity and abdominal obesity, independent of diet.

Evaluation of the ceramic laminate veneer-tooth interface after different resin cement excess removal techniques.

OBJECTIVES: To compare, in vitro, resin cement excess removal techniques at the veneer-tooth interface. MATERIALS AND METHODS: Anterior human teeth were restored with ceramic veneers and randomly divided according to the following techniques (n = 10): removal of excess resin cement with brush and dental floss, followed by light-curing with Valo (Group 1) or Elipar (Group 2) for 1 min and 40 s; tack-curing with Valo (Group 3) or Elipar (Group 4) for 1 s; and tack-curing with Valo (Group 5) or Elipar (Group 6) for 5 s. The tack-curing was followed by removal of excess with probe and dental floss and light-curing for 1 min and 40 s. The area of excess resin cement (mm2) was measured in micro-CT images using AutoCAD program. The failures at the cervical margin in the X, Y, and Z axes (µm) of greater value were measured using the DataViewer program. The specimens were submitted to microleakage with 2% basic fuchsin. RESULTS: According to the Kruskal-Wallis and multiple comparison test, the highest area of excess resin cement was found in Group 1 (5.06 mm2), which did not differ statistically from Groups 2 (3.70 mm2) and 5 (2.19 mm2). Groups 2, 3 (1.73 mm2), 4 (1.14 mm2), and 5 (2.18 mm2) did not differ statistically. Group 6 (0.77 mm2) obtained the lowest value, which did not differ statistically from Groups 3 and 4. According to the Kruskal-Wallis and Dunn test, there was no significant difference in failures in X (p = 0.981), Y (p = 0.860), and Z (p = 0.638) axes and no significant difference in microleakage (p = 0.203) among the groups. CONCLUSIONS: Tack-curing for 1 s or 5 s, followed by removal of excess resin cement using a probe and a dental floss, tended to result in a lower amount of excess material around the margin. CLINICAL RELEVANCE: The technique used for resin cement excess removal influences the amount of excess leaved at the veneer-tooth interface. Tack-curing for 1 s or 5 s is recommended to mitigate the excess resin cement.

Factors associated with the mortality of women living with HIV: a case-control study.

This case-control study investigated factors associated with death among women living with HIV (WLHIV) in the city of Porto Alegre/RS, Brazil. Sociodemographic, parental and reproductive characteristics, exposure to HIV, laboratory markers and adherence to treatmen were variables examined. The cases were selected among WLHIV who were followed up by health care services for the vertical transmission of HIV (VT) and who died between the years of 2007 and 2017. The controls were the WLHIV who did not die. Sixty-six cases and 264 controls were included. Conditional Logistic Regression was conducted to estimate the Crude and Adjusted Odds Ratio. A conceptual block model was considered for the multivariate analysis. In addition to multiple pregnancies and worse immunological characteristics, WLHIV between 18 and 29 years of age (OR = 25.72; 95% CI: 4.45-148.42), drug users (OR = 7.09; 95% CI: 1.24-40.23) and who were not followed up during prenatal care (OR = 8.43; 95% CI: 1.58-44.87) were more likely to die. Conclusion: Young WLHIV and those with greater social vulnerability have a greater chance of death, and it is essential that health care and treatment strategies consider actions for the prevention of deaths taking into account the multiple vulnerabilities of these women.

Prevalence and factors associated with excessive and severe daytime sleepiness among healthcare university students in the Brazilian Midwest.

The present study aimed to determine the prevalence of, and factors associated with excessive and severe daytime sleepiness in healthcare university students. A cross-sectional university-based study was conducted with 1,779 students from a university located in the Brazilian Midwest State of Goiás, Brazil, in 2018. Daytime sleepiness was assessed using the Epworth Sleepiness Scale (ESS) and classified as excessive daytime sleepiness (EDS; cut-off ESS score ≥10) and severe EDS (S-EDS; cut-off ESS score ≥16). Associated factors included sociodemographic, behavioural, academic, nutritional status, and sleep-related and perceived health characteristics. Poisson regression was used for the data analysis. The mean (SD) age of the sample was 22.5 (3.84) years. The prevalence of EDS was 54.4% (95% confidence interval [CI] 51.9-56.1) and S-EDS was 10.0% (95% CI 9.2-11.7). After adjustment, a higher probability of occurrence of EDS was found among women (prevalence ratio [PR] 1.37, 95% CI 1.24-1.53), younger students (PR 1.23, 95% CI 1.07-1.42), those who were studying medicine (PR 1.14, 95% CI 1.02-1.28), with poor sleep quality (PR 1.29, 95% CI 1.17-1.43), and among those who reported constant loss of sleep due to internet use (PR 1.14, 95% CI 1.02-1.27). After adjustment, the highest probability of occurrence of S-EDS was found among women (PR 1.72, 95% CI 1.22-2.43), among those with poor sleep quality (PR 2.17, 95% CI 1.54-3.08), and medical students (PR 1.39, 95% CI 1.01-1.90). In conclusion, there was a high prevalence of daytime sleepiness among healthcare university students, especially among medical students and women.

Structural validity of the Brazilian version of the Sense of Coherence scale (SOC-13) in oral health research: exploratory and confirmatory factor analysis.

BACKGROUND: The Sense of Coherence (SOC) construct has been used worldwide in oral health research, but rigorous factor analyses of the scale are scarce. We aim to test the dimensional structure of the Brazilian short version of the SOC scale with 13 items. METHODS: This study is a secondary analysis of four independent cross-sectional Brazilian studies on oral health, using the 13-items SOC scale. Sample 1 was conducted on 1760 mothers and 1771 adolescents. Sample 2 comprised 1100 adults. Sample 3 had 720 adults and older individuals. Sample 4 comprised 664 adolescent students. Confirmatory Factor Analysis (CFA) was conducted on sample 1 to compare two models: 3-factor versus 1-factor. Because they were refuted, Exploratory Factor Analysis was implemented in samples 2 and 3. Modified models were tested in sample 4 using CFA. All analyses were conducted with MPlus version 7.11. RESULTS: CFA of sample 1 resulted in an unacceptable fit (RMSEA = 0.12;CFI = 0.78; TLI = 0.73; and WRMR = 3.28) for 1-factor model and 3-factor (RMSEA = 0.10; CFI = 0.87; TLI = 0.84; and WRMR = 2.50). The EFA on samples 2 and 3 showed, respectively, two eigenvalues greater than 1 (4.11 and 1.56) and (4.32 and 1.42), but the scale items soc1, soc2 and soc3 formed an uninterpretable second factor. Another CFA, using sample 4, showed acceptable model fit after removing those three items and also soc11 (RMSEA = 0.05; CFI = 0.98; TLI = 0.99; and WRMR = 0.71). CONCLUSION: The results indicate that the SOC-13 scale needs further adjustments. The one-factor model with nine items showed a good statistical fit, but the implications of excluding items should be further investigated, considering the scale's content validity, cross-cultural adaptation and theoretical background.

Quality of life in young and middle age adult temporomandibular disorders patients and asymptomatic subjects: a systematic review and meta-analysis.

AIMS: To compare the difference in the quality of life between temporomandibular disorders (TMD) patients and non-TMD subjects diagnosed with the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) or the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD). METHODS: Medical Literature Analysis and Retrieval System Online (MEDLINE), Excerpta Medica database (EMBASE) and Latin American and Caribbean Health Sciences Literature (LILACS) databases were searched in studies published in English and Portuguese. The search was performed by two independent reviewers in duplicate. A manual search and the gray literature were also included. The inclusion criteria were clinical studies that used the RDC/TMD axis I and quality of life with standard questionnaires in young and middle-aged adult population (18-55 years). The data were analyzed quantitatively by combining the results in a meta-analysis using forest plots. The measure of effect used was the standardized mean difference (SMD) in depression levels. The Newcastle-Ottawa Scale (NOS) was used to evaluate the quality of the studies. The publication bias was assessed by funnel plots. The initial search included 806 articles without duplications. RESULTS: Twenty-four articles were included in the final systematic review. Of these, 9 were included in the meta-analysis, where it was shown a statistically significant in all axis I groups: (a) global TMD-groups I, II and III combined, N = 3829, SMD (95% CI) = 1.06 (0.65-1.51), p = 0.000; (b) group I-muscle disorders, N = 3,056, SMD (95% CI) = 0.82 (0.45-1.18), p = 0.000; (c) group II-disc displacements, N = 3,184, SMD (95% CI) = 0.59 (0.26-0.91), p = 0.000; and (d) group III-arthralgia/arthritis/arthrosis, N = 2781, SMD (95% CI) = 0.98 (0.59-1.36), p = 0.000. When compared to controls. CONCLUSIONS: Quality of life is affected in all axis I TMD patients, especially in groups I and III with higher pain intensity and disability as compared to group II.

Parental Monitoring of Computer Use and its Association with Drug Use among Students in Southern Brazil.

BACKGROUND: Parental control is considered important in preventing drug use among adolescents. OBJECTIVE: This study aimed to explore the association between the perception of parental monitoring of computer use and drug use among adolescent students. METHODS: A cross-sectional school-based study was conducted in 2012 among 2,980 students aged 12-17 years from Southern Brazil. The outcomes investigated were the use of tobacco, alcohol, cannabis, and other illicit drugs in the previous year. The main exposure was the self-reported perception of parental monitoring of computer use. Poisson regression with robust variance was used for the multivariable analysis. RESULTS: The prevalence rates of drugs used were 48.3% (95% confidence interval[CI]: 46.5-50.0) for alcohol, 9.7% (95%CI: 8.7-10.7) for tobacco, 5.1% (95%CI: 4.3-5.9) for cannabis, and 8.7% (95%CI: 7.7-9.7) for other illicit drugs. The absence of monitoring of computer use was reported by 44.3% (95%CI: 42.5-46.1) of the students. After adjusting for potential confounders, we found that students aged 12 to 14 years who reported no parental monitoring of computer use had a higher probability of alcohol (Prevalence Ratio[PR] = 1.26, 95%CI:1.07-1.49) and cannabis use (PR = 3.25, 95%CI:1.11-9.53). In addition, a higher consumption of tobacco was observed among students aged 15 to 17 years who reported no parental monitoring of computer use (PR = 1.75, 95%CI:1.17-2.63). In both age groups, psychiatric morbidity was a covariate significantly associated with drug use throughout analysis. CONCLUSIONS: Parental monitoring of computer use was significantly associated with adolescent drug use, suggesting its importance in preventing drug use.

Subjective sleep quality and temporomandibular disorders: Systematic literature review and meta-analysis.

STUDY OBJECTIVES: To assess the general subjective sleep quality in individuals with and without TMD, and its distribution among the TMD diagnostic groups. METHODS: A systematic review search was performed in Pubmed/MEDLINE, Embase, LILACS, Web of Science, SciELO, CINAHL and Cochrane Central as well as in the grey literature. Observational studies published since 1992 which used either the DC/TMD or RDC/TMD for TMD diagnosis and either the PSQI, SAQ or ESS questionnaires for sleep assessment were included. Articles selected for meta-analysis underwent quality, heterogeneity and publication bias evaluation. RESULTS: A total of 1071 articles were found by online search, and 10 articles were added manually. For full-text reading, 138 papers were selected. Thirty-six articles were included in the final review, and 19 in the meta-analysis (PSQI only). Subjective sleep quality was shown to be associated with all RDC/TMD or DC/TMD Axis I diagnostic groups: muscle disorders, arthralgia/osteoarthritis/osteoarthrosis and disk displacements; with the highest association in the first two groups, and the lowest in the last one. A 4.45 times increased odds ratio of TMD prevalence was found for individuals who presented poor subjective sleep quality. CONCLUSION: Subjective sleep quality should be considered in the management of TMD.

Shift work, sleep duration, and body image dissatisfaction among female workers in southern Brazil.

We examined the association between shift work and sleep duration with body image dissatisfaction (BID) among shift-working women in southern Brazil. In this cross-sectional study, data of 505 women shift workers, between 18 and 60 years old, were collected between January and April 2011. BID was assessed using the Stunkard Figure Rating Scale. Information on shift work, sleep duration, and other explanatory variables was collected through a questionnaire. An aggregated exposure variable was created and termed "sleep deprivation," with the exposure category being night-shift workers who slept < 7 h/day. The respective prevalence ratio values were estimated using a Poisson regression. The prevalence of BID among shift-working women was 42.4 (95% CIs = 38.0 to 46.7%), and 199 (93.0%) of these women wished they had a smaller body size. Shift work (PR = 1.40; p = 0.006) and sleep duration (PR = 1.32; p = 0.010) were independently associated with BID. Additionally, workers with sleep deprivation exhibited a higher probability of BID than those without sleep deprivation (PR = 1.31; p = 0.012). These results reveal a situation of vulnerability and the need for strategies and actions directed at shift-working women with the aim of reducing the effects of sleep deprivation on mental health, particularly with regard to body image disorders.

Salivary Cortisol, Perceived Stress, and Metabolic Syndrome: A Matched Case-Control Study in Female Shift Workers.

Although the pathogenesis of metabolic syndrome (MetS) is complex and multifactorial, there is limited information if psychological factors, such as stress exposure, are involved in the etiology of MetS. Therefore, this study investigated the associations between MetS and cortisol levels and perceived stress levels among women shift workers in Southern Brazil. A matched case-control study was conducted, including 50 cases of MetS and 200 age-matched controls (±3 years, 4 for each case). Salivary cortisol levels were evaluated immediately after waking and one upon returning home from work. Perceived stress levels were measured by the Perceived Stress Scale with 10 items (PSS-10). Multivariate-adjusted associations between MetS and salivary cortisol levels and perceived stress levels were assessed by conditional logistic regression. Means±standard deviations of salivary cortisol levels were not significantly different between cases and controls either immediately after waking (5.37±4.10 vs. 6.03±5.39 nmol/l; p = 0.53) or after work (2.74±2.87 vs. 2.78±2.85 nmol/l; p = 0.93). There was no significant difference in perceived stress level between cases and controls (14.2±5.9 vs. 15.5±5.6; p = 0.15). No independent association was observed in the multivariate model between MetS and salivary cortisol level or perceived stress level after these exposures were stratified into tertiles. Overall, there was no difference between women with or without MetS in regard to the free salivary cortisol and perceived stress. Our results do not support an association between stress exposure and MetS among women shift workers.

Gender differences in the prevalence of household food insecurity: a systematic review and meta-analysis.

OBJECTIVE: The present review aimed to identify and synthesize literature on household food insecurity with respect to whether the respondent was male or female. DESIGN: A systematic review of prevalence studies followed by a meta-analysis was conducted between 28 August 2014 and 19 October 2014 in seven electronic databases. The search was updated in April 2016. The included studies used experience-based measures to assess household food insecurity. Dichotomous measures of food insecurity were used. Pooled odds ratios of household food insecurity prevalence in women v. men were obtained through random-effect modelling. Quality assessment, publication bias diagnostics and subgroup analysis were also performed. SETTING: Population-based studies (i.e. non-clinical populations). SUBJECTS: Participants aged 18 years or over. RESULTS: Out of the 5145 articles initially identified, forty-two studies with a total population of 233 153 were included. In general, results showed that the odds for household food insecurity was 40 % higher in studies where women were the respondent (95 % CI 1·27, 1·54; P<0·001). Besides, subgroup analysis revealed that female-headed households were 75% (95 % CI 49-96%) more likely to be food insecure than male-headed households. CONCLUSIONS: Our results confirm the existence of gender differences in reporting household food insecurity. Furthermore, they indicate that households headed by women constitute a segment of the population that is particularly vulnerable to food insecurity.

Workplace social capital, mental health and health behaviors among Brazilian female workers.

OBJECTIVE: Previous studies have investigated the relationship between workplace social capital and mental health, yet few have sought to examine the mediating mechanisms. We sought to explore the role of workplace social capital on health related behaviors and on mental health among female employees in Brazil. METHODS: A cross-sectional study was undertaken with 553 women aged 28-50 years working in the production line of a poultry processing plant. We assessed workplace social capital, common mental disorders, stress (Perceived Stress Scale) and health related behaviors (physical activity, healthy eating habits and co-occurrence of risk behaviors). We used structural equation modeling to clarify relationships between exposures, outcomes, and mediating variables. RESULTS: Our model demonstrated a direct effect of social capital on the outcomes studied. Higher workplace social capital was associated with lower stress and common mental disorders as well as more favorable health-related behaviors. Our model also showed an indirect effect of social capital on mental health and on behaviors that was mediated by lower levels of perceived stress. CONCLUSION: Workplace social cohesion may play an important role in the promotion of mental health and healthy behaviors among women employees.

Physical activity in adolescence and abdominal obesity in adulthood: a case-control study among women shift workers.

Physical activity may have a protective effect against abdominal obesity, an important risk factor for cardiometabolic diseases. Thus, the aim of this study was to examine the association between the practice of physical activities in adolescence and abdominal obesity in adulthood among women shift workers in Southern Brazil in 2011. This case-control study included 215 cases (waist circumference greater than or equal to 88 cm) and 326 controls. For both the case and control groups, participation in leisure-time physical activities was most frequent in adolescence and was significantly less in adulthood. After adjusting for potential confounding factors, women who participated in five or more physical activities in adolescence were 50 percent less likely to have abdominal obesity than women who participated in one activity or no physical activities (Odds Ratio = 0.50; 95% confidential interval: 0.27-0.93, p value = .029). Participation in various types of leisure-time physical activities in adolescence may protect against abdominal obesity in adulthood, even if the number of physical activities decreases over time. This finding demonstrated the importance of physical activity as well as the period of life in which these should be encouraged for the prevention of health disorders, such as abdominal obesity.

Sleep deprivation and obesity in shift workers in southern Brazil.

OBJECTIVE: The objective of our study was to explore the association between sleep deprivation and obesity among shift workers. DESIGN: A cross-sectional study was conducted. Obesity was defined as BMI ≥30 kg/m2. Time of sleep was categorized as: >5 h of continuous sleep/d; ≤5 h of continuous sleep/d with some additional rest (sleep deprivation level I); and ≤5 h of continuous sleep/d without any additional rest (sleep deprivation level II). Sociodemographic, parental and behavioural variables were evaluated by means of a standardized pre-tested questionnaire. Potential confounding factors were controlled for in the multivariable model. SETTING: A poultry-processing plant in southern Brazil. SUBJECTS: Nine hundred and five shift workers (63 % female). RESULTS: Obesity was more prevalent in the participants who were female, aged 40 years and older, who had less schooling and reported excess weight in both parents. Sleep deprivation levels I and II were associated with increased income, number of meals consumed throughout the day and nightshift work. All of the workers who exhibited a degree of sleep deprivation worked the night shift. After controlling for potential confounding factors, the prevalence ratios of obesity were 1·4 (95 % CI 0·8, 2·2) and 4·4 (95 % CI 2·4, 8·0) in the workers with sleep deprivation levels I and II, respectively, compared with the reference group. CONCLUSIONS: These results show a strong association between sleep deprivation and obesity in shift workers and that sleep deprivation may be a direct consequence of working at night.

Depression and the risk of developing temporomandibular disorders in different diagnostic groups: A systematic review with meta-analysis.

OBJECTIVE: To evaluate the role of depression in the development of TMD groups. METHODS: This systematic review with meta-analysis compared the prevalence and scores of depression between TMD groups and controls. RESULTS: The results showed that depression was a significant risk factor in the development of RDC/TMD axis I muscle disorders (group I) and arthralgia/osteoarthritis/osteoarthrosis (group III), and non-significant for disc displacements (group II). Severe depression had almost four times the risk of developing TMD as compared to moderate depression. CONCLUSION: These findings suggest that addressing psychological factors in general, and depression in particular, in the managemenof TMD is crucial, especially in those TMD groups with higher pain levels (I and III), and the TMD pain reduction is crucial in reducing depression levels.

The association between self perceptions of psychological well-being and overweight in Brazilian children.

Our objective was to estimate the prevalence and test the association between psychological well-being and overweight in children. We conducted a cross-sectional study using anthropometrical measures and interviews with 1048 6-10-year-old school children from a Brazilian town. Overweight was assessed by the body mass index and included obesity. Psychological data of children and their parents were collected using a face scale. Poisson regression models were used to test the associations and to obtain unadjusted and adjusted prevalence ratios (PR). The prevalence of overweight was of 15.3% (95% CI: 13.2-17.6) and of only obesity was 3.8% (2.8-5.2). After controlling for age, sex, school type and parental overweight, the prevalence of overweight was 52% and 44% higher in children who reported a psychological dissatisfaction in themselves and in their mothers when compared with those with positive self perception (PR = 1.52 95% CI = 1.02-2.28; P = 0.038) and (PR = 1.44 95% CI = 1.00-2.09; P = 0.049), respectively. The study suggests that actions aiming weight control of children should take into account psychological aspects of children and their families.

Years of potential life lost due to AIDS in female, in Southern Brazil: a descriptive study, 2007-2017. / Anos potenciais de vida perdidos por aids no sexo feminino, no Sul do Brasil: estudo descritivo, 2007-2017.

OBJECTIVE: to describe the years of potential life lost (YPLL) due to AIDS among the female population and analyze its association with race/skin color and social vulnerability indicators in Porto Alegre, capital city of the state of Rio Grande do Sul, Brazil. METHODS: this was a descriptive study that took into consideration AIDS deaths in female between 2007 and 2017; data were obtained from the Mortality Information System; crude values and YPLL rates per 1,000 deaths were calculated, taking into consideration health districts and race/skin color. RESULTS: of the 1,539 deaths, approximately 51,000 years of potential life were estimated, representing 86.5 years lost/1,000 female; it could be seen a higher proportion of deaths among female of White race/ skin color (53.4%); however, a higher rate of YPLL was found among female of Black and mixed race/skin color living in regions of greater vulnerability. CONCLUSION: the results suggest the impact of racial inequalities on the decrease in years of potential life due to AIDS deaths.

Evidence of the validity of the Multidimensional Scale of Perceived Social Support (MSPSS) in university students. / Evidências de validade da Escala Multidimensional de Suporte Social Percebido (EMSSP) em universitários.

Social support refers to the social resources that a person perceives to be available and has been strongly associated with physical and mental health outcomes. The present study aimed to evaluate the internal consistency, construct validity, and test-retest reliability of the Perceived Social Support Multidimensional Scale (PSSMS) in university students in the Midwest of Brazil. Exploratory and confirmatory factor analyses were performed with two independent random samples, both consisting of 1,147 students. The test-retest study was carried out with a sample of 347 medical students. Data were collected in two separate moments with a 14-day interval. The solution with the best fit was the three-factor model: family, friends, and significant others. The factor loadings of the scale items ranged between 0.767 and 0.950 and each factor showed high internal consistency (Cronbach's alpha=0.96, 0.97, and 0.97, respectively). The model also attained adequate fit: χ2(d.f.)=380 (49), p<0.0001; SRMR=0.023; RMSEA=0.077; CFI=0.993; TLI=0.990. Test-retest reliability was moderate (weighted kappa ranging from 0.36 to 0.52). The results suggest that the PSSMS has acceptable psychometric properties for use with university students.

O apoio social se refere aos recursos sociais percebidos como disponíveis à pessoa e tem sido fortemente associado a desfechos em saúde física e mental. O estudo atual objetivou avaliar a consistência interna, a validação de construto e a confiabilidade teste-reteste da Escala Multidimensional de Suporte Social Percebido (EMSSP) em universitários do Centro Oeste brasileiro. As análises fatoriais exploratória e confirmatória foram realizadas com duas amostras aleatórias e independentes, ambas de 1.147 universitários da área da saúde. O estudo teste-reteste foi realizado com uma amostra de 347 estudantes de medicina e duas coletas com intervalo de 14 dias entre elas. A melhor solução foi com três fatores: família, amigos, e outros significativos, os quais apreesentaram cargas fatoriais variando entre 0,767 a 0,950 e consistência interna elevada (alfa de Cronbach de 0,96, 0,97 e 0,97, respectivamente). O ajustamento para essa solução foi adequado (χ2(g.l.)=380 (49), p<0,001; SRMR: 0,023; RMSEA: 0,077; CFI: 0,993; TLI: 0,990). A confiabilidade teste-reteste foi moderada (Kappa ponderado variando de 0,36 a 0,52). Os resultados sugerem que a EMSSP possui propriedades psicométricas aceitáveis para seu uso com universitários.

[Validity and reliability of the 8-item EUROHIS-QOL to assess Brazilian adults' quality of life]. / Validade e confiabilidade do EUROHIS-QOL 8-item para avaliar a qualidade de vida em adultos brasileiros.

The study evaluated the psychometric properties of the EUROHIS-QOL 8-item scale in Brazilian adults. The EUROHIS-QOL is a measurement of quality of life developed based on the generic instruments of WHOQOL-100 and WHOQOL-BREF. Based on data from a prospective cohort of 1,100 adults, participants in the baseline in 2006 and 2007, exploratory factor analysis, internal consistency, reliability, and discriminant validity were performed via multitrait-multimethod analysis, with the calculation of the average variance extracted (AVE). Confirmatory factor analysis was conducted with 573 of these participants in 2013 to 2018. Solutions were tested with one and with two factors named functional capacity and socioeconomic conditions. Both solutions presented good internal consistency and reliability. The correlation between the items was 0.535, and the AVE was 0.397 for solution with one factor, and 0.528 and 0.341 for factors one and two, respectively, indicating good discriminant validity in the bifactorial solution. Both factors had eigenvalues greater than one and factor loadings ranging from 0.398 to 0.915. The adjustment of the unifactorial solution presented: χ2 = 186 (g.l. = 18), p < 0.001, RMSEA = 0.128 (90%CI: 0.111-0.145), CFI = 0.960, TLI = 0.938, and SMRM = 0.042; while in the bifactorial presented: χ2 = 135 (g.l. = 17), p < 0.001, RMSEA = 0.110 (90%CI: 0.093-0.128), CFI = 0.972, TLI = 0.954, and SMRM = 0.035. Overall, the results provide reasonable evidence for the construct validity and reliability of the EUROHIS-QOL 8-item. Instruments with fewer items, as in our case, provide greater practicality and are ideal for use in population-based studies with extensive samples.

O estudo avaliou as propriedades psicométricas da escala EUROHIS-QOL 8-item em adultos brasileiros. O EUROHIS-QOL 8-item é uma medida de qualidade de vida desenvolvida a partir dos instrumentos genéricos WHOQOL-100 e WHOQOL-BREF. A partir dos dados de uma coorte prospectiva com 1.100 adultos participantes da linha de base em 2006 e 2007, foram realizadas análise fatorial exploratória, consistência interna, confiabilidade e validade discriminante por meio da análise multitraço-multimétodo, com o cálculo das variâncias médias extraídas (AVE). A análise fatorial confirmatória foi conduzida com 573 desses participantes nos anos de 2013 a 2018. Foram testadas soluções com um e com dois fatores nomeados capacidade funcional e condições socioeconômicas. Ambas as soluções apresentaram boa consistência interna e confiabilidade. A correlação entre os itens foi de 0,535 e as AVE foram 0,397 para solução com um fator, e 0,528 e 0,341 para os fatores um e dois, respectivamente, indicando boa validade discriminante na solução bifatorial. Os dois fatores tiveram autovalores maiores que um e cargas fatoriais variando de 0,398 a 0,915. O ajustamento da solução unifatorial foi: χ2 = 186 (g.l. = 18), p < 0,001, RMSEA = 0,128 (IC90%: 0,111-0,145), CFI = 0,960, TLI = 0,938 e SMRM = 0,042; enquanto na bifatorial era: χ2 = 135 (g.l. = 17), p < 0,001, RMSEA = 0,110 (IC90%: 0,093-0,128), CFI = 0,972, TLI = 0,954 e SMRM = 0,035. De modo geral, os resultados fornecem evidências razoáveis da validade de construto e confiabilidade do EUROHIS-QOL 8-item. Instrumentos com menor número de itens, como é o caso, proporcionam maior praticidade e são ideais para utilização em estudos de base populacional com uso de amostras extensas.

El estudio evaluó las propiedades psicométricas de la escala EUROHIS-QOL 8-ítems (Europe Health Interview Surveys Quality of Life Abbreviated Instrument) en adultos brasileños. El índice de 8 ítems EUROHIS-QOL es una medida de calidad de vida desarrollada con base en los instrumentos genéricos WHOQOL-100 (World Health Organization Quality of Life Instrument) y WHOQOL-BREF (World Health Organization Quality of Life Abbreviated Instrument). Con base en los datos de una cohorte prospectiva de 1.100 adultos que participaron en la línea de base en 2006 y 2007, se realizaron los análisis factorial exploratorio, de consistencia interna, de confiabilidad y de validez discriminante mediante un análisis multirrasgo-multimétodo, con el cálculo de la varianza media extraída (AVE). Se realizó un análisis factorial confirmatorio con 573 de estos participantes de 2013 hasta 2018. Se probaron soluciones de uno y dos factores denominados capacidad funcional y condiciones socioeconómicas. Ambas soluciones presentaron buena consistencia interna y confiabilidad. La correlación entre los ítems fue de 0,535 y las AVE fueron de 0,397 para la solución de un factor y de 0,528 y 0,341 para los factores uno y dos, respectivamente, lo que indica una buena validez discriminante en la solución bifactorial. Los dos factores tuvieron autovalores mayores a uno y cargas factoriales que oscilaron entre 0,398 y 0,915. El ajuste de la solución unifactorial fue: χ2 = 186 (g.l. = 18), p < 0,001, RMSEA = 0,128 (IC90%: 0,111-0,145), CFI = 0,960, TLI = 0,938 y SMRM = 0,042; mientras que en la bifactorial fue: χ2 = 135 (g.l. = 17), p < 0,001, RMSEA = 0,110 (IC90%: 0,093-0,128), CFI = 0,972, TLI = 0,954 e SMRM = 0,035.

Prevalence of Premenstrual Syndrome and Associated Factors Among Academics of a University in Midwest Brazil.

OBJECTIVE: To investigate the prevalence of premenstrual syndrome (PMS) and premenstrual dysphoric disorder (PMDD) in university students, the factors associated with PMS, the most prevalent symptoms, and the interference of symptoms in academic, family, social, and work activities. METHODS: This cross-sectional study included 1,115 university students aged ≥ 18 years from the University of Rio Verde, Goiás. Premenstrual syndrome and PMDD were identified using the Premenstrual Symptoms Screening Tool. Associations with sociodemographic, behavioral, reproductive, nutritional, and health factors were investigated using the Poisson regression. RESULTS: The prevalence of PMS was 46.9% (95% confidence interval [CI] 44.0-49.8), and of PMDD, 11.1% (95% CI 9.3-13.0). The most prevalent symptoms were physical, such as breast tenderness, bloating, e weight gain (73%); followed by psychological ones such as overeating/food cravings, tearful/more sensitive to rejection (> 60%). More than 30% of the patients reported that the symptoms interfered in a moderate-to-severe way in their social and academic activities. After adjusted analysis, PMS was more prevalent in those who were attending the 1st/2nd semester of college (prevalence ratio [PR] 1.44; 95% CI 1.14-1.80), those who consumed alcohol in the last 30 days (PR 1.23; 95% CI 1.04-1.47), and those who had depression (PR 1.49; 95% CI 1.30-1.71). CONCLUSION: Almost half of the university students had PMS and ∼ 11%, PMDD. Physical symptoms were the most common and interfered in a moderate-to-severe way in various aspects of life. Attending the first semesters, consuming alcohol, and having depression were risk factors for PMS. The identification of risk factors for PMS is essential to prevent symptoms and reduce the impact of the syndrome.

OBJETIVO: Investigar a prevalência de síndrome pré-menstrual (SPM) e do transtorno disfórico pré-menstrual (TDPM) em alunas universitárias, os fatores associados à SPM, os sintomas mais prevalentes e a interferência dos sintomas nas atividades acadêmicas, familiares, sociais e de trabalho. MéTODOS: Este estudo transversal incluiu 1.115 estudantes universitárias ≥ 18 anos da Universidade de Rio Verde, Goiás. Síndrome pré-menstrual e TDPM foram identificados por meio do Premenstrual Symptoms Screening Tool. As associações com fatores sociodemográficos, comportamentais, reprodutivos, nutricionais e de saúde foram investigadas utilizando-se a regressão de Poisson. RESULTADOS: A prevalência de SPM foi de 46,9% (intervalo de confiança [IC] de 95% 44,0­49,8) e de TDPM, 11,1% (IC 95% 9,3­13,0). Os sintomas mais prevalentes foram físicos, como sensibilidade mamária, distensão abdominal e ganho de peso (73%); seguidos por psicológicos, como comer demais/desejos por comida, chorar/mais sensível à rejeição (> 60%). Mais de 30% relataram que os sintomas interferiam de forma moderada a grave em suas atividades sociais e acadêmicas. Após análise ajustada, a SPM foi mais prevalente naquelas que estava cursando o 1°/2° semestre da faculdade (razão de prevalência [RP] 1,44; IC 95% 1,14­1,80), as que haviam consumido álcool nos últimos 30 dias (RP 1,23; IC 95% 1,04­1,47), e as que tinha depressão (RP 1,49; IC 95% 1,30­1,71). CONCLUSãO: Quase metade das universitárias tinha SPM e cerca de 11%, TDPM. Os sintomas físicos foram os mais comuns e interferiram de forma moderada a grave em vários aspectos da vida. Frequentar os primeiros semestres, consumir álcool e ter depressão foram fatores de risco para SPM. A identificação dos fatores de risco para a SPM é essencial para prevenir os sintomas e reduzir o impacto da síndrome.
