Obesity prevalence in Brazilian firefighters and the association of central obesity with personal, occupational and cardiovascular risk factors: a cross-sectional study.

ABSTRACT: OBJECTIVES:This study aimed to investigate the obesity prevalence in a population of Brazilian firefighters and the association of central obesity (CO) with sociodemographic, occupational, life habits, fitness and health status variables. DESIGN:Cross-sectional study. SETTINGS:The data were collected during annual health inspections of firefighters from the Military Fire Service of the State of Espírito Santo, a state in Southeast Brazil. PARTICIPANTS:The study encompassed 1018 active military firefighters. After exclusion criteria, 892 male firefighters were analysed. PRIMARY AND SECONDARY OUTCOME MEASURES:The collected data included: sociodemographic, occupational, lifestyle, fitness and health status variables. The associations between these factors and CO were calculated by adjusted OR through a hierarchical logistic regression model. RESULTS:Obesity estimation by body mass index indicated that 48.65% of the firefighters were overweight and 10.99% were obese. Concerning the body fat percentage, 26.23% of the participants were considered obese, while 18.61% of the firefighters were considered centrally obese or at risk using the waist circumference measure. After adjusted OR analysis, CO was more likely associated with the age range of 50 to 59 years old (OR 2.93; 95% CI 1.05 to 8.14), low self-reported physical activity (OR 1.95; 95%?CI 1.14 to 3.34), low cardiorespiratory fitness (OR 5.15; 95%?CI 3.22 to 8.23), hyperglycaemia (OR 1.70; 95%?CI 1.07 to 2.72) and hypertriglyceridaemia fasting status (OR 3.12; 95%?CI 1.75 to 5.55). CONCLUSIONS:Our study identified an overall high prevalence of overweight and obese individuals in the examined firefighter population. Age and cardiovascular risk factors were directly associated with CO among the firefighters. Cardiovascular risk factors should be routinely inspected within the Brazilian firefighters' corporations in order to improve the health condition and wellness of these workers. These endeavours will improve the performance of the services provided to the population.

Project description:BackgroundEvidence from previous studies suggests that women firefighters have greater risk of some adverse reproductive outcomes. The purpose of this study was to investigate whether women firefighters had greater risk of miscarriage compared to non-firefighters and whether there were occupational factors associated with risk of miscarriage among firefighters.MethodsWe studied pregnancies in the United States fire service using data from the Health and Wellness of Women Firefighters Study (n = 3181). We compared the prevalence of miscarriage among firefighters to published rates among non-firefighters using age-standardized prevalence ratios. We used generalized estimating equations to estimate relative risks (RRs) and 95% confidence intervals (CIs) between occupational factors (employment (career/volunteer), wildland firefighter status (wildland or wildland-urban-interface/structural), shift schedule, fire/rescue calls at pregnancy start) and risk of miscarriage, adjusted for age at pregnancy, education, gravidity, BMI, and smoking. We evaluated if associations varied by age at pregnancy or employment.ResultsAmong 1074 firefighters and 1864 total pregnancies, 404 pregnancies resulted in miscarriages (22%). Among most recent pregnancies, 138 resulted in miscarriage (13%). Compared to a study of US nurses, firefighters had 2.33 times greater age-standardized prevalence of miscarriage (95% CI 1.96-2.75). Overall, we observed that volunteer firefighters had an increased risk of miscarriage which varied by wildland status (interaction p-value< 0.01). Among structural firefighters, volunteer firefighters had 1.42 times the risk of miscarriage (95% CI 1.11-1.80) compared to career firefighters. Among wildland/wildland-urban-interface firefighters, volunteer firefighters had 2.53 times the risk of miscarriage (95% CI 1.35-4.78) compared to career firefighters.ConclusionsAge-standardized miscarriage prevalence among firefighters may be greater than non-firefighters and there may be variation in risk of miscarriage by fire service role. Further research is needed to clarify these associations to inform policy and decision-making.

Project description:BackgroundObesity at the workplace has been associated with symptoms of lower self-esteem, increased individual and employer healthcare costs, increased absenteeism and presenteeism and reduced productivity. Therefore, this study was designed to study the prevalence and correlates of central obesity among formal sector employees in Dodoma City.MethodsStudy design was a cross-sectional survey conducted from March to June, 2019. Participants were employees from formal sector employment defined as those paid regular monthly wage and with either a secured permanent or temporary contract. Simple random sampling was used to select four out of fifteen large buildings hosting various establishments. Respondents were obtained conveniently and interviewed face to face. Central obesity was defined as a waist circumference greater than 102 cm for males and greater than 88 cm for females. Chi-square test was conducted to assess the differences among the groups. Simple and multiple logistic regression models were fitted to identify the correlates of central obesity.ResultsA total of 392 respondents (98% response rate) agreed and participated in the study. The overall prevalence of central obesity was found to be 41.8% (164/392). The prevalence of central obesity was significantly higher among females (67.4% p < 0.001), respondents aged ≥51 years (60%, p = < 0.001), administrators (55.1% p = < 0.05), respondents with salary of > 1,000,000 Tanzanian Shilling (TSh.) per month (54.4%, p = < 0.05), respondents who eat homemade meals at the workplace (64.2%, p = < 0.05) and respondents with hypertension (62.5%, p = < 0.05). Correlates of central obesity were found to be female sex (AOR = 9.53; 95% CI: 5.49, 16.78), increased age, eating homemade meals at the workplace (AOR = 2.32; 95% CI: 1.04, 4.19) and hypertension (AOR = 3.15; 95% CI: 1.41, 6.91).ConclusionsThe present study revealed high prevalence of central obesity among formal sector employees in Dodoma City. Scholars and stakeholders are urged to generate more evidences and design appropriate interventions to curb the situation.

Project description:ObjectivesIt is important to ascertain which anthropometric measurements of obesity, general or central, are better predictors of cardiovascular disease (CVD) risk in women. 10-year CVD risk was calculated from the Framingham risk score model, SCORE risk chart for high-risk regions, general CVD and simplified general CVD risk score models. Increase in CVD risk associated with 1 SD increment in each anthropometric measurement above the mean was calculated, and the diagnostic utility of obesity measures in identifying participants with increased likelihood of being above the treatment threshold was assessed.DesignCross-sectional data from the National Heart Foundation Risk Factor Prevalence Study.SettingPopulation-based survey in Australia.Participants4487 women aged 20-69 years without heart disease, diabetes or stroke.Outcome measuresAnthropometric obesity measures that demonstrated the greatest increase in CVD risk as a result of incremental change, 1 SD above the mean, and obesity measures that had the greatest diagnostic utility in identifying participants above the respective treatment thresholds of various risk score models.ResultsWaist circumference (WC), waist-to-hip ratio (WHR) and waist-to-stature ratio had larger effects on increased CVD risk compared with body mass index (BMI). These central obesity measures also had higher sensitivity and specificity in identifying women above and below the 20% treatment threshold than BMI. Central obesity measures also recorded better correlations with CVD risk compared with general obesity measures. WC and WHR were found to be significant and independent predictors of CVD risk, as indicated by the high area under the receiver operating characteristic curves (>0.76), after controlling for BMI in the simplified general CVD risk score model.ConclusionsCentral obesity measures are better predictors of CVD risk compared with general obesity measures in women. It is equally important to maintain a healthy weight and to prevent central obesity concurrently.

Project description:BackgroundObesity and overweight are known public health problems that affect populations across the world. These conditions have been associated with a wide range of chronic diseases including type 2 diabetes mellitus, cardiovascular disease, and cancers. In Ethiopia, the literature regarding the burden of central (abdominal) obesity is scarce. This study aimed to fill this gap by assessing the prevalence and risk factors associated with central obesity among adults in Ethiopia.MethodsFrom May to July 2021, a community-based cross-sectional survey was conducted on a sample of 694 adults aged ≥18 years in administrative towns of Bale zone, Southeast Ethiopia. Multi-stage sampling followed by systematic random sampling was employed to identify study participants. Waist and hip circumferences were measured using standard protocols. The World Health Organization STEPS wise tool was used to assess risk factors associated with central obesity. Bi-variable and multi-variable binary logistic regression were used to identify factors associated with central obesity. Adjusted odds ratios (AOR) and their corresponding 95% confidence intervals (CI) have been reported to estimate the strength of associations.ResultsThe overall prevalence of central obesity using waist circumference was 39.01% [(95% CI: 35.36-42.76; 15.44% for men and 53.12% for women)]. Multi-variable binary logistic regression analysis revealed that female sex (AOR = 12.93, 95% CI: 6.74-24.79), Age groups: 30-39 years old (AOR = 2.8, 95% CI: 1.59-4.94), 40-49 years (AOR = 7.66, 95% CI: 3.87-15.15), 50-59 years (AOR = 4.65, 95% CI: 2.19-9.89), ≥60 years (AOR = 12.67, 95% CI: 5.46-29.39), occupational status like: housewives (AOR = 5.21, 95% CI: 1.85-14.62), self-employed workers (AOR = 4.63, 95% CI: 1.62-13.24), government/private/non-government employees (AOR = 4.68, 95% CI: 1.47-14.88), and skipping breakfast (AOR = 0.46, 95% CI: 0.23-0.9) were significantly associated with central obesity.ConclusionsAbdominal obesity has become an epidemic in Bale Zone's towns in Southeastern Ethiopia. Female sex, age, being employed were positively associated with central obesity, while skipping breakfast was a protective factor.
