The Magnitude of Salt Intake Behaviors and Its Predictors among Saqez Urban Population of Kurdistan District in Iran: A Cross-Sectional Study.

BACKGROUND: Controlling and reducing salt intake are one of the solutions to overcome hypertension. This study aimed at determining the predictors related to salt control methods in Saqez urban population. METHODS AND MATERIALS: In the present cross-sectional study, the sample population was randomly selected through cluster sampling. Data collection was performed using valid questionnaires, demographic, family economic status, knowledge, perception, intention, salt intake behaviors, and salt control methods, along with measuring body mass index (BMI) and hypertension levels. Descriptive, analytical statistical methods and multivariate logistic regression analysis were used to determine the predictors of desirable salt control methods. The variables of sex, age, family economic status, knowledge, perception, perceived social support, self-efficacy, and intention were analyzed as independent variables. Data analysis was performed using SPSS software version 24 at a significance level of 0.05. RESULTS: Out of 766 participants, 73% were women, with mean (M) 32.83, standard deviation (SD) 9.52 years, and 77.2% were married. There were significant sex differences in employment (P=0.01) and economic status (P=0.016). The M (SD) of blood pressure (systolic/diastolic) was 110.65 (0.0212) (P=0.441). The salt intake control methods between men and women did not show significant differences (P=0.368). Among totally 88.5%, 87.7% men and 88.9% women followed desirable behaviors. The predictors that determine the adoption of salt control methods were sex (man) (OR = 0.71, 95% CI (0.38-1.29)), age (OR = 1.02, 95% CI = (0.99-1.05)), SES/FAS (medium, high level) (OR = 1.37, 95% CI = (0.754-2.47); OR = 0.46, 95% CI = (0.047-4.55)), blood pressure (OR = 1.33, 95% CI = (0.16-11.23)), knowledge (have) (OR = 1.01, 95% CI = (0.39-1.63)), intent to reduce salt (OR = 1.047, 95% CI = (1.03-1.06)), perceived salt reduction importance (OR = 1.02, 95% CI = (1.01-1.04)), perceived emotional support (health staff) (OR = 1.02, 95% CI = (1.01-1.04)), media (OR = 1.01, 95% CI = 0.99-1.02), perceived practical support (spouse) (OR = 1.02, 95% CI = 0.99-1.04)), and perceived self-efficacy (OR = 1.01, 95% CI = (0.99-1.03)). CONCLUSION: The support of health staff and spouse seems to be effective in controlling the salt intake behaviors of healthy individuals. In parallel with the development and change of people's lifestyles, new approaches (legal and services) for salt control based on the support of media and social media were expected.

Frequency of Smear-Negative Tuberculosis in Northwest Iran.

BACKGROUND: Microscopic smear examination is the most common test in tuberculosis (TB) detection. It is, however, not strong enough to identify TB in the majority of afflicted individuals; thus, a significant number of TB patients are smear negative and capable of transmitting the infection. The aim of this study was to evaluate the rate of smear-negative TB in northwest Iran. METHODS: In this cross-sectional study, 329 TB-confirmed patients were evaluated through culture up to March 1, 2015, in northwest Iran. The demographic and clinical features of the smear-negative and smear-positive TB patients were compared. The χ2 test was used to compare the frequency of the variables. All the statistical analyses were conducted using SPSS, version 16 (Chicago, IL, USA). RESULTS: Seventy-five cases were smear negative and 254 were smear positive. Smokers, asthmatics, and extra-pulmonary TB patients were primarily among the smear-negative cases. The rate of mortality was also relatively higher among the smear-negative TB patients. CONCLUSION: Totally, 22.8% of the TB cases in northwest Iran were smear negative, with a relatively higher rate of mortality than those with positive smears. A delay in these patients' return to TB diagnosis and treatment centers increases the chance of transmission to others. This is a very sensitive issue in centers where there is no equipment for TB cultivation. Thus, it is essential to equip centers without TB cultivation facilities and to use appropriate diagnostic techniques in centers with those facilities to help rapidly detect smear-negative cases.

Conversion of extrinsic into intrinsic motivation and computer based testing (CBT).

BACKGROUND: Because computers are used in many aspects of today's life, it seems necessary to include them in teaching and assessment processes. METHOD: The aims of this cross-sectional study were to construct a multidimensional valid scale, to identify the factors that influenced the nature of student motivation on Computer Based Testing (CBT), to recognize how students self-regulated their activities around CBT, and to describe the efficiency of autonomous versus controlled situations on motivation. The study was carried out among 246 Iranian Paramedical Students of Tabriz Medical Sciences University, Tabriz, Iran; 2013-2014. The researchers prepared a questionnaire, based on the Self-Determination Theory (SDT), containing 26 items with a five-point Likert scale. It was prepared according to a previous valid questionnaire and by sharing opinions with some students and five professors. The factor analysis was done to perform instructional and exploratory factor analysis. RESULTS: The Kaiser-Meyer-Olkin(KMO) measure was performed and variables were correlated highly enough to provide a reasonable basis for factor analysis. The selected 4 factors determined a 60.28% of the variance; autonomy 26.37%, stimulation 14.11%, relatedness10.71%, and competency 9.10%. CONCLUSION: A questionnaire was prepared and validated, based on SDT variables. The results indicated that autonomous extrinsic motivation correlated positively with intrinsic motivation and CBT. There was a general positive attitude towards computer-based testing among students. As students became intrinsically motivated through the promotion of autonomous regulation, CBT was recommended as a proper test mode.

Social support and dairy products intake among adolescents: a study from Iran.

BACKGROUND: Adequate daily milk and dairy products intake seems to an important for adolescents' health. This study aimed to identify the high-risk group adolescents who did not meet the recommended daily serving milk and dairy products and indeed to find out associated factors relating to their nutrition behaviors. METHODS: This cross sectional study was carried out on 7th grade students, in Tabriz, East Azerbaijan province, Iran. An anonymous self-administrated questionnaire including items on perceived social support, physical activity, and sedentary behaviors was administered. In addition a valid food frequency questionnaire (FFQ) measuring daily milk products serving intake as a main outcome measure was completed for each respondent. Logistic regression analysis was applied to examine the association between milk and dairy products consumption and independents variables. RESULTS: In all 402 students (51.5 % female) participated in the study. The mean age of students was 12.9 (SD = 0.49) years. The average daily intake of milk and dairy products was 1.64 (SD = 0.78) servings per day. Overall 14.2 % of adolescents (18.8 % of girls, and 9.2 % of boys, p = 0.006) reported consumption of the recommended daily milk and dairy products serving per day. The results indicated that gender boys (OR for boys = 2.41, 95 % CI = 1.25-4.67), mother age (OR for age group 40-55 years = 2.52, 95 % CI = 1.18-5.38), poor perceived emotional family support, (OR = 1.10, 95 % CI = 1.05-3.61), and poor perceived practical family support (OR = 2.04, 95 % CI = 1.18-4.17) were the most significant contributing factors to low level milk and dairy products intake in adolescents. CONCLUSION: The findings indicated that adolescents did not take the recommended daily amount of milk and dairy products and this appeared to be strongly related to low perceived family support. To achieve the recommended daily milk and dairy products serving consumption, family involvements in any programs that specifically address emotional and practical support for promoting daily milk and dairy products intake among adolescents are suggested.
