Background: This study aimed to determine the prevalence of chronic pain and its contributing factors among teenagers aged 12-21 years in Shiraz, Iran. Methods: This cross-sectional study was conducted on adolescents aged 12-21 years. Demographic variables of the adolescents and their parents as well as the pain characteristics were assessed. Descriptive statistics, multinomial logistic regression, and regression models were used to describe the characteristics of the pain and its predictive factors. Results: The prevalence of chronic pain was 23.7%. The results revealed no significant difference between the male and female participants regarding the pain characteristics, except for the home medications used for pain relief. The results of a chi-square test showed that the mother's pain, education, and occupation, and the father's education were associated significantly with chronic pain in adolescents (P < 0.05). Multinomial logistic regression also showed the mother's history of pain played a significant role in the incidence of adolescents' chronic pain. Conclusions: The prevalence of chronic pain was relatively high in these adolescents. The results also provided basic and essential information about the contributing factors in this area. However, consideration of factors such as anxiety, depression, school problems, sleep, and physical activity are suggested in future longitudinal studies.

The purpose of this study was to compare the nutrient intake of elderly according to their cohabitation status and determine its effects on the prevalence of anemia. Data from the KNHANES were used for this study, including raw data on socioeconomic characteristics, nutrient intake, health status, and clinical laboratory findings. Study subjects aged 60 to 80 years were retrieved and analyzed. As a result, the prevalence of anemia was 12.0% (men, 11.6%; women, 12.3%). The prevalence rate increased with age, and odds ratio [OR] of anemia among those aged 75 to 80 years was 4.16 times higher in men (OR=4.16, 95% confidence interval [CI]=2.48-6.97) and 2.77 times higher in women (OR=2.77, 95% CI=1.86-4.14) compared to 60~64 years old. Socioeconomic factors (area of residence, education level, household income), including cohabitation Status (living alone VS living with other family members), and health behaviors (high-risk drinking, smoking, aerobic exercise) did not significantly effect on anemia. In addition, other than protein intake for men, nutrient intake did not have a significant effect on the prevalence rate of anemia. Hypertension, diabetes, and cancer significantly increased the risk of anemia. In Korea, the influencing factors of elderly anemia change over time, so periodic follow-up studies are needed.

PURPOSE: This study examined the anthropometric and clinical risk factors and the prevalence of sarcopenia in women aged 40 to 49 years. METHODS: The study design is a cross-sectional research and a total of 2,055 participants were included. The participants were divided into two groups based on their skeletal muscle mass index score. One hundred and twenty-six individuals were assigned to a sarcopenia group, and 1,939 were assigned to a normal group. The following variables were analyzed: age, height, weight, body mass index, waist circumference, skeletal muscle mass index anthropometric measure, systolic blood pressure, diastolic blood pressure, blood laboratory tests, fasting glucose, triglyceride, total cholesterol, and smoking and drinking smoking statuses. RESULTS: The prevalence of sarcopenia was 6.5% (95% CI: 5.33-7.92). Anthropometric variables, such as height, BMI, and waist circumference, showed significance differences between the two groups (p < .05), except for weight variable (p > .05). In terms of blood pressure and blood lab tests, the systolic blood pressure, diastolic blood pressure, fasting glucose, triglyceride, and total cholesterol were all significant risk factors for sarcopenia in the two groups. (p < .05). CONCLUSION: This study identified risk factors and the prevalence of sarcopenia among community-dwelling middle-aged women.

Objectives: The incidence of cardiovascular disease (CVD) mortality is increasing in developing countries. This study aimed to decompose the socioeconomic inequality of CVD in Iran. Methods: This cross-sectional population-based study was conducted on 20 519 adults who enrolled in the Ardabil Non-Communicable Disease cohort study. Principal component analysis and multivariable logistic regression were used, respectively, to estimate socioeconomic status and to describe the relationships between CVD prevalence and the explanatory variables. The relative concentration index, concentration curve, and Blinder-Oaxaca decomposition model were used to measure and decompose the socioeconomic inequality. Results: The overall age-adjusted prevalence of CVD was 8.4% in northwest Iran. Multivariable logistic regression showed that older adults, overweight or obese adults, and people with hypertension and diabetes were more likely to have CVD. Moreover, people with low economic status were 38% more likely to have CVD than people with high economic status. The prevalence of CVD was mainly concentrated among the poor (concentration index, -0.077: 95% confidence interval, -0.103 to -0.060), and 78.66% of the gap between the poorest and richest groups was attributed to differences in the distribution of the explanatory variables included in the model. Conclusions: The most important factors affecting inequality in CVD were old age, chronic illness (hypertension and diabetes), marital status, and socioeconomic status. This study documented stark inequality in the prevalence of CVD, wherein the poor were more affected than the rich. Therefore, it is necessary to implement policies to monitor, screen, and control CVD in poor people living in northwest Iran.

A cross-sectional study was conducted to investigate the prevalence of canine influenza (CI) infection in pet dogs and canine parvovirus (CPV) infection in street dogs of different age and sex by collecting rectal and nasal swab samples from three districts, Dhaka, Mymensingh and Sirajgonj, in Bangladesh using a RapiGEN$^{(R)}$ Canine Influenza Virus Ag Test kit and RapiGEN$^{(R)}$ Canine Parvovirus Ag Test Kit. Out of 114 rectal swabs and 115 nasal swab samples, the overall prevalence of CI and CPV was found to be 11.30% and 32.45%, respectively. The prevalence of parvovirus infection was found to be significantly higher in puppies and dogs 6 months of age (50.0%) than those > 24 months of age (p = 0.005). The prevalence was also higher in males (34.42%) than females (30.18%). The prevalence of CI was higher (30.43%) in dogs up to 6 months of age (p = 0.011) than 6-12 month (7.93%) and 12-18 month (6.66%) old dogs. Moreover, the prevalence of CI was found to be higher in males (16.10%) than females (5.66%). The prevalence of CPV infection also varied significantly in different study areas (p = 0.0029), with 12.72%, 12.5% and 7.14% of dogs found to be CI positive in Dhaka, Mymensingh and Sirajgonj, respectively. Overall, the highest prevalence of CI was found in local breeds (6.08%) followed by German shepherds and Keeshonds (1.73%), and Bloodhounds and Terriers (0.86%). Additionally, there were more positive CI found in unvaccinated dogs (14.81%) than vaccinated (2.94%) dogs. Dogs with flu-like symptoms were more positive (19.23%) for CI relative to those without flu-like symptoms (4.76%) samples. Overall, the results of this study indicate that canine vaccination should be initiated to prevent the occurrence of diseases and that regular monitoring should be continued in Bangladesh.

Cardiovascular disease is very prevalent in Korea, and many risk factors, if properly identified are possibly corrected. However, the study results on prevalence and distribution of risk factors may not be reliable while the risk factors of disease are always issued on health promotion projects conducted recently in a community. The subjects of this study were 854 adults who participated in the health and nutrition survey in a community. They were aged between 20 and 69 and sampled representatively. This study intended to estimate the prevalence and the distribution of risk factors of cardiovascular disease such as hypertension, diabetes mellitus, hypercholesterolemia, and obesity. Systolic blood pressure and diastolic blood pressure levels were estimated at $123.9{\pm}2.2mgHg(men)$, $117.9{\pm}1.7mgHg$(women), and $80.4{\pm}1.5mg(men)$, $74.9{\pm}1.1mgHg(women)$, respectively. Glucose level was estimated at $99.1{\pm}2.3mg/dl$ in men, and $95.7{\pm}1.7mg/dl$ in women. The estimated level of total cholesterol and HDL-cholesterol were $183.4{\pm}3.8mg/dl(men)$, $181.7{\pm}3.1mg/dl(men)$, and $122.0{\pm}4.5mg/dl(women)$, and body mass index was estimated at $24.0{\pm}0.4kg/m^2$ in men and $23.9{\pm}0.4kg/m^2$ in men and $23.9{\pm}0.3kg/m^2$ in women. The prevalence of hypertension was 20.5% for men, and 14.4% for women. The prevalence of diabetes mellitus was estimated to 6.9% for men, and 6.1% for women. The estimated prevalence of hypercholesterolemia was 3.8%(men), 3.9%(women). The rate of obesity was estimated to 28.5%(men), 28.4% (women), respectively. The levels of blood pressure, glucose, and cholesterol were higher in men than in women in almost all the almost ate groups. The prevalence of hypertension for men is about 20%. It was found that the prevalence of diabetes mellitus for males aged between 40 and 59 was rapidly increased. The risk factor with highest prevalence was obesity, and hypertension and diabetes mellitus were the second and third most prevalent.

In the past decade there has been increasing concern about the atopic dermatitis (AD) associated with environmental diseases. AD has been increased in the last decade and known as one of the multifactoral diseases, which has the genetic background and environmental factors at the same time. The purposes of this study were to investigate the prevalence rate and etiologic risk factors of atopic dermatitis in preschool children in Changwon, which is a one of the Korean cities and has a large industrial complex. We reviewed and analyzed the statistical data, obtained from Korea National Health Insurance Corporation, related to prevalence rate by age and administrative district. A cross-sectional questionnaire survey, based on ISAAC (International Study of Allergy and Asthma in Childhood), was conducted on random samples of preschool children (5 to 8 years old) of large sized kindergartens in Changwon. The lifetime and last one years prevalence of AD in preschool children in Changwon was increased from 1998 to 2008. The prevalence rate of AD in the preschool children in Changwon city was 9.6%. The prevalence rate in boys was 9.7% and that in girls was 9.4%. The one year prevalence of AD was ranked as middle among other provincial cities in Korea in 2008. This study showed that the prevalence rate of the atopic disease in Changwon was 9% in 2008, which was increased especially compare to 2000. More active governmental approaches for control and prevention of atopic dermatitis for children are recommended. Further studies are needed for more accurate estimation of the prevalence of AD in Korea including different regional and age population.

The prevalence of some swine reproductive and zoonotic diseases in Colombia is unknown, making their management difficult. This study assessed the prevalence of porcine circovirus type 3 (PCV3), Leptospira interrogans, pseudorabies virus, and porcine gamma-herpesvirus by polymerase chain reaction in sows in the productive stage, from farms with a history of reproductive failures, at the department of Tolima. The prevalence of PCV3 was 2.6% and 12.6% for L. interrogans, with some samples co-infected with PCV2. Owing to the coinfections with PCV2, it is necessary to establish whether the interactions between these pathogens were related to the presence of reproductive problems.

Objective: The smoking prevalence in Malaysia is high, especially among men and adolescents. This study aimed to determine the prevalence and associated factors towards cigarette smoking among school teachers in Malaysia. Methodology: This study was a school-based cross-sectional study conducted among 495 secondary school teachers. The questionnaire used in this study consisted of 29 questions categorized into two sections: socio-demographic characteristics and smoking behaviour. Data were analyzed using the Statistical Package for the Social Sciences (SPSS) program 13.0. ANOVA; t-tests were used in univariate analysis; multiple linear regression was applied for multivariate analysis. Results: The majority of the participants were female (81.6%), in the age group ranged between 30-39 years (44%), Malay (90.1%), married (89.7%), degree holders (85.1%), with monthly income ranged between 3000-3999 Ringgit Malaysia (33.5%), from urban areas (94.7%), their specialty is social studies (33.9%) and with no family history of cancer (83.6%). The prevalence of smoking among school teachers in Malaysia was found to be 7.8%. Regarding reasons to start smoking among school teachers: the major reason was found to be relaxation (33.3%), followed by stress-relief (28.2%). Univariate analysis showed that sex, educational status, monthly income and residency were significantly associated with smoking among school teachers (p<0.001, p=0.004, p=0.031, p=0.010; respectively). Multivariate analysis showed that gender and marital status were significantly associated with smoking among school teachers (p<0.001, p=0.033; respectively). Conclusion: The prevalence of smoking among school teachers in Malaysia was found to be relatively low. Sex, marital status, educational status, monthly income and residency were significantly associated with smoking among school teachers.
