Prevalence of overweight, obesity, and associated risk factors in healthy female adolescents in Tehran, Iran

Introduction: Obesity is an important health concern worldwide and is a growing problem in Iran. Adolescent  obesity has a major role in development of adulthood obesity and its complications. The present study was conducted to evaluate the prevalence of overweight, obesity, and associated risk factors in female adolescents living in Tehran, Iran.Methods: This cross-sectional study was carried out among 2,132 female adolescents aged 14-17 years in Tehran recruited between 2017 and 2018. Weight and height were measured and body mass index (BMI) was calculated. Underweight, overweight, and obesity were considered as < 5th, ? 85th, and ? 95th percentile, respectively, of CDC BMI-for age and sex criteria. Adolescents and their mothers filled in the questionnaires on physical activity, computer use, duration of breastfeeding, total sleep time, and family socioeconomic status. Statistical analysis was performed using SPSS version 22.0 software. P < 0.05 was considered statistically significant.Results: The overall prevalence rates of overweight and obesity were 24.1% and 6.5%, respectively. The prevalences of overweight and obesity were highest in the South District (28.9% and 7.7%, respectively) and were lowest in the North District (19.1% and 5.2%, respectively). There were significant differences in physical activity level (P < 0.001), total sleep time (P < 0.001), duration of breastfeeding (P < 0.01), and daily computer use (P < 0.001) among the four groups (underweight, normal, overweight, and obese). Regarding the socioeconomic status, parental education level and economic status were significantly higher in those who had normal weight compared to other weight groups (in both, P < 0.001).Conclusion: This study showed that overweight and obesity among female adolescents in Tehranhave become a major public health concern. Level of physical activity, computer use, sleep duration, breastfeeding duration, levels of parental education, and economic status were associated with overweight and obesity prevalence

Oral health status and associated lifestyle behaviors in a sample of Iranian adults : an exploratory household survey

Background Poor oral hygiene can lead to serious diseases, such as periodontitis, tooth decay, pain and discomfort in teeth or gums, infections, and loss of teeth. In Iran, adults aged 50 y and older are a high-risk group for oral health problems, and this age group will grow in the coming decades. Despite increasing attention on healthy aging, there is relatively less emphasis on oral hygiene and health-related problems. The present study investigated the oral health status of Iranian adults using the oral health self-assessment questionnaire (OHQ) developed by the World Health Organization (WHO). Methods A population-based household survey of a sample of adults aged 18-65 y was conducted. In this study, the participants were recruited between May and October 2016 in Tabriz, Iran, and the study population was sampled using a multi-stage cluster sampling design. The WHO's OHQ for adults was used for measuring oral health status and oral hygiene behavior. Results In total, 2310 respondents completed the survey. The mean age (SD) of the participants was 41.6(23.4) y. Males accounted for 48.8% of the participants. Of the 2310 respondents,187 (8.1%) individuals were edentulous, 152(20.7%) of whom were aged 51-65 y. Furthermore, 72.3% of those aged 51-65 y were dentate, and 50% of adults aged 51-65 y said they had 20 or more teeth. About one-third of the participants reported that they did not brush their teeth daily (23% of those aged 18-35 y,35.9% of those aged 36-50 y, and 44.6% for those aged 51-65 y). In the sample, 39.4% of individuals aged 18-35 y,34.1% of individuals aged 36-50 y, and 26.6% of individuals aged 51-65 y had visited a dentist less than 6 month ago. One-third of the participants consumed sweets and sugary drinks daily. Conclusions Although the majority of Iranian adults considered their oral health status good, only a small percentage of the sample visited their dentist regularly. Furthermore, visits to the dentist declined in accordance with increasing age, a time when the incidence of oral health problems may increase. Poor oral health may increase the risk of adverse health outcomes, particularly among the aging population

Predictors of poor blood pressure control among Iranian hypertensive patients

Abstract Objective The aim of this study is to investigate factors associated with poor blood pressure (BP) control in older hypertensive patients living in Iran. Poorly controlled hypertension was defined as blood pressure greater than or equal to 140/90 mmHg. Multiple logistic regressions were performed to identify factors associated with poor BP control. Results More than half of the patients (55.1%) had poor control of hypertension. Multivariate logistic regression analysis showed that being over 60 years of age (OR 1.67; 95% CI 1.18–2.37; p = .003), being widowed or divorced (OR 1.56; 95% CI 1.03–2.35; p = .035], smoking (OR 1.78; 95% CI 1.07–2.65; p = .01], BMI > 25 kg/m2 (OR 1.51 95% CI 1.05–2.78), having a waist circumference ≥ 90 cm (OR 1.7; 95% CI 1.2–2.42; p = .003], the use of calcium channel blockers (OR 2.69; 95% CI 1.26–5.72; p = .01], and the use of angiotensin converting enzyme inhibitors (OR 1.66; 95% CI 1.01–2.72; p = .044] contributed significantly to poor control of hypertension. Making a key BP control screening target (such as age over 60 and waist circumference of 90 cm or more) for cardiovascular specialists and other health care practitioners is needed for elderly patients at risk for poor BP control

Gender Differences Time Trends for Metabolic Syndrome and Its Components among Tehranian Children and Adolescents

Aims. To investigate the trend of metabolic syndrome and its components in Tehran children and adolescents during a median followup of 6.6 years. Methods. Data from 1999–2001 (phase I), 2002–2005 (phase II), and 2006–2008 (phase III) of the Tehran, Lipid and Glucose Study were analyzed (n = 5439; age 6–18 years) for the trend of metabolic syndrome (MetS) and its components. General estimation equation (GEE) models were used to analyze this correlated data. Results. The crude prevalence of MetS for boys at baseline was 13.2%, which increased to 16.4% in the third phase. In girls, the prevalence of Mets decreased from 11.8% at baseline to 6% during followup. The odd ratios (OR) of obesity over the whole study period were raised in both sexes. The OR of abdominal obesity increased significantly in boys, but no change was observed in girls. No significant OR was observed in boys, while OR for MetS was shown to have a decreasing trend in girls during the followup. In the three time points, the ORs of MetS decreased significantly in girls but no significant difference was observed in boys. Conclusion. Inspite of increasing trend for obesity in both sexes, the trend of MetS decreased in girls and was relatively stable in boys, in Tehranian children, and adolescents

Lipid ratios and appropriate cut off values for prediction of diabetes: a cohort of Iranian men and women

<p>Abstract</p> <p>Background</p> <p>Dyslipidemia is a risk factor for incident type 2 diabetes; however, no study has specifically assessed the lipid ratios (i.e. total cholesterol (TC)/high density lipoprotein cholesterol (HDL-C) and triglyceride (TG)/HDL-C) as predictors of diabetes. We aimed to compare the independent association between the different lipid measures with incident diabetes over a median follow up of 6.4 years in Iranian men and women.</p> <p>Method</p> <p>The study population consisted of 5201 non diabetic (men = 2173, women = 3028) subjects, aged ≥20 years. The risk factor adjusted odds ratios (ORs) for diabetes were calculated for every 1 standard deviation (SD) change in TC, log-transformed TG, HDL-C, non-HDL-C, TC/HDL-C and log-transformed TG/HDL-C using multivariate logistic regression analysis. Receiver operator characteristic (ROC) curve analysis was used to define the points of the maximum sum of sensitivity and specificity (MAXss) of each lipid measure as a predictor of diabetes.</p> <p>Result</p> <p>We found 366 (146 men and 220 women) new diabetes cases during follow-up. The risk-factor-adjusted ORs for a 1 SD increase in TG, TC/HDL-C and TG/HDL-C were 1.23, 1.27 and 1.25 in men; the corresponding risks in females were 1.36, 1.14, 1.39 respectively (all p < 0.05, except TC/HDL-C in females which was marginally significant, p = 0.07). A 1 SD increase of HDL-C only in women decreased the risk of diabetes by 25% [0.75(0.64-0.89)]. In both genders, there was no difference in the discriminatory power of different lipid measures to predict incident diabetes in the risk factor adjusted models (ROC ≈ 82%). TG cutoff values of 1.98 and 1.66 mmol/l; TG/HDL-C cutoff values of 4.7 and 3.7, in men and women, respectively, TC/HDL-C cutoff value of 5.3 in both genders and HDL-C cutoff value of 1.18 mmol/l in women yielded the MAXss for defining the incidence of diabetes.</p> <p>Conclusion</p> <p>TC/HDL-C and TG/HDL-C showed similar performance for diabetes prediction in men population however; among women TG/HDL-C highlighted higher risk than did TC/HDL-C, although there was no difference in discriminatory power. Importantly, HDL-C had a protective effect for incident diabetes only among women.</p

Prevalence of metabolic syndrome and its determinants among Iranian adults : evidence of IraPEN survey on a bi-ethnic population

Metabolic syndrome (MetS) is a growing public health concern worldwide. It has been demonstrated that individuals with MetS are at an increased risk of cardiovascular events and diabetes. We aimed to investigate the prevalence of MetS and its components among Turkic and Kurds ethnic groups in a bi-ethnic (Turk and Kurd) population. This cross-sectional study is part of the national health transformation plan created in response to the emerging epidemic of non-communicable diseases (Iran's Package of Essential Non-communicable Disease study), launched in 2014 in Naqadeh, Iran. In total, 3506 participants aged 30-70 years were randomly included in the study from urban and rural regions. Cardio-metabolic risk factors related to MetS diagnosis and other related sociodemographic factors were assessed for men and women in both the Turk and the Kurd population. Multivariate logistic regressions were applied to identify MetS-associated factors among both the Turk and the Kurd population. The mean (SD) age of the participants was 49.6 (12.3) years. Of the participants, 56.2% (n = 1969) were women, and 43.8% (n = 1537) were men. Three-fifths of the participants were Turk (60.3%, n = 1751). The overall prevalence of MetS was 37.05%, with a higher prevalence in women (49.8% versus 24.3% in men). The prevalence of MetS and its components among Turk people (41.6%) were significantly higher than that among Kurd people (33.9%) (p < 0.0001). In addition, the prevalence of MetS was higher among women, urban, and older people for both ethnicities. Strong associations were found between MetS prevalence and being older, being female, being overweight, being obese, having a higher waist-to-hip ratio, and having a history of diabetes and cardiovascular disease (CVD) in the family for both Turks and Kurds. The raised waist circumference (WC) is the most prevalent MetS component for Turk men and women. Meanwhile, the most prevalent MetS component for Kurd participants is low high-density lipoprotein for women and a raised WC for men. Significant differences were found between Kurdish men and women for all components, except for a raised WC and a raised fasting blood glucose (p < 0.05). Because the Iranian population features multiple ethnicities, the recognition of the prevalence of MetS components is a major step in establishing intervention strategies for modifying cardio-metabolic risk factors based on the population ethnicities and their sociodemographic, cultural, and lifestyle factors. We recommend future studies for planning an efficient and sustainable health education and promotion program to halt MetS prevalence

Detection of Functional Limitation in Diabetic Patients Based on the Optimal Combination of Care Indicators Using Ramp AUC and Comparing its Performance With the Existing Methods

Objectives: The area under the ROC curve (AUC) is a common criterion to assess the overall classification performance of the markers. In practice, due to the limited classification ability of a single marker, we are interested in combining markers linearly or nonlinearly to improve classification performance. Ramp AUC (RAUC) is a new statistical AUC-based method which can find such optimal combinations of markers. In this study, RAUC was used to find the optimal combinations of care indicators related to functional limitation as a complication of diabetes and accurately discriminate this outcome based on its underlying markers. Materials and Methods: This cross-sectional study was conducted on 378 diabetic patients referred to diabetic centers in Ardebil and Tabriz during 2014 and 2015. To have an accurate classification of diabetic patients according to their functional limitation status, RAUC method with RBF kernel was employed to look for an optimal combination of care indicators. Classification performance of the model was evaluated by AUC and compared with logistic regression, support vector machine (SVM) and generalized additive model (GAM) via training and test validation method. Results: Out of 378 diabetics, 67.46% had functional limitation. RAUC had an AUC of 1 for the test dataset and outperformed logistic (AUC = 0.079), GAM (AUC = 0.082), SVM with linear kernel (AUC = 0.67) and was slightly better than SVM with RBF kernel (AUC = 0.98). Conclusions: There was a strong nonlinearity in data and RAUC with RBF kernel which is a nonlinear combination of markers could detect this patter

Resilience and its relationship with exposure to violence in emergency nurses

Background: Workplace violence (WPV) is a detrimental factor affecting nurses' health and performance. Individual protective factors such as resilience can assist nurses in coping with and adapting to workplace adversity. Objectives: The present study was aimed to determine the relationship between resilience and exposure to WPV in emergency nurses. Methods: This cross-sectional study was carried out on 118 emergency nurses in Tabriz educational hospitals, Iran. The participants were selected through a convenience sampling method. A demographic questionnaire, the Conner-Davidson Resilience Scale, and the Modified Questionnaire of Workplace Violence in the health sector were used for data collection. The data were analyzed using descriptive statistics, logistic regression analysis, t-test, and one-way analysis of variance. Results: The mean resilience score of nurses was 25.05 ± 5.79 in the possible range of 0-40. Most of the cases of violence were verbal threats (80.5), and 56.7 of the exposures occurred during the night shift. Logistic regression showed that lower resilience predicted verbal threats (P = 0.001) and physical attacks (P = 0.038) against the individual. In addition to resilience, working on the night shift significantly predicted verbal threats (P = 0.008) against nurses. Conclusion: The resilience score was lower in nurses who exposed to violence. Empowerment programs are suggested to improve the resilience of nurses

Prevalence of smoking, alcohol consumption, and drug abuse in Iranian adults: Results of Azar Cohort Study

Background: Substance abuse has significant health impacts on families and society as a whole. We aimed to provide detailed prevalence estimates of substance abuse among the Azar Cohort Study respondents in Tabriz, Iran. Methods: Data on 15006 participants of Azar Cohort Study were analyzed. The variables included tobacco smoking, alcohol use, drug abuse, and socio-demographic characteristics. The prevalence of substance abuse (with a 95% confidence interval) was calculated using the direct standardization method. Results: Overall, 9.3% and 6.2% of the participants were regular and heavy cigarette smokers, respectively. Also, 1.9% and 2.1% of participants reported a history of using illicit drugs and alcohol, respectively. Substance abuse was more prevalent among males than females. Substance abuse varied significantly with age and socioeconomic variables. Conclusion: We identified specific demographic and socioeconomic groups with a higher prevalence of all studied behaviors. Such high-risk groups should be targeted when designing substance abuse prevention programs
