The Ergonomic Behaviors Evaluation Tool (EBET) based on social cognitive theory for the assembly line workers: development and psychometric assessment.

BACKGROUND: Ergonomic behaviors play a crucial role in preventing work-related musculoskeletal disorders (WMSDs). To measure these behaviors, this research aimed to develop and evaluate an ergonomic behaviors tool (EBET) based on the Social Cognitive Theory (SCT) among women workers on assembly lines (WwAL). METHODS: The study was conducted from December 2022 to January 2023 with a focus on the psychometric assessment of EBET. Initially, a literature review and interviews were carried out to identify crucial concepts and primary items. The questionnaire's validity was evaluated using the Content Validity Ratio (CVR) and the Content Validity Index (CVI). To determine the domains of the tool, construct validity was examined by administering the items to 270 eligible women. The reliability of the tool was assessed using McDonald's Omega coefficient. RESULTS: From a total of 67 primary items, 50 were confirmed. The study demonstrated good validity with CVR = 0.92 and CVI = 0.97, along with reliable results indicated by McDonald's Omega coefficient of 0.74. The exploratory factor analysis (EFA) revealed ten distinct dimensions: outcome expectations, outcome expectancies, normative beliefs, perceived barriers, social support, observational learning, reinforcement, behavioral skills, self-efficacy, and intention. Together, these dimensions accounted for 66.25% of the variance in the data. Additionally, the confirmatory factor analysis results supported the presence of these ten constructs and demonstrated a satisfactory fit. CONCLUSIONS: EBET is a dependable and valid instrument for evaluating the ergonomic behaviors of workers, utilizing the principles of SCT. Researchers can employ EBET to gather data and implement suitable training interventions to enhance ergonomic behavior among WwAL. However, it is crucial to recognize that EBET may not encompass all facets of ergonomic behaviors. Therefore, it is imperative for future research to prioritize the evaluation of EBET's suitability among diverse worker populations and to consider additional dimensions of ergonomics to ensure its wider applicability and effectiveness.

Effectiveness of a theory-based back care intervention on spine-related behavior among pupils: a school-based randomised controlled trial (T-Bak study).

BACKGROUND: Children's health and welfare have a special place in research and policy in many countries. One of the most important concerns is the increasing rate of backache in children due to many of behavioral risk factors. The aim of this study was to evaluate the effectiveness of an educational program on promoting back-related behavior as well as knowledge, skills, beliefs, and self-efficacy among fifth grade girls. METHODS: The theory-based back care (T-Bak) study was a school-based randomised controlled trial (RCT) that assessed the effectiveness of developing a back care training program based on the social cognitive theory (SCT). A total of 104 schoolchildren aged 11 ± 1.0 years were assigned to intervention (n = 52) and control (n = 52) groups. The intervention group received six sessions training on proper lifting and carrying techniques, having proper posture during daily activities, and correct backpack wearing techniques with a 1-week interval while the control group received nothing. Then, the two groups were assessed for knowledge, skills, self-efficacy, beliefs, and behavior at four points in time: baseline, immediate, three and six-months post-intervention. The changes of the outcomes investigated using univariate repeated measures analysis of variance. Partial eta squared measure (ηp2) was used to calculate effect sizes. RESULTS: A positive change was found for the intervention group back-related behavior from baseline to immediate post-intervention and follow-ups (F = 78.865, p < 0.001, ηp2 = 0.22). Overall there were 36.4% improvement for knowledge (ηp2 = 0.21), 53.2% for the skills (ηp2 = 0.25), 19.5% for the self-efficacy (ηp2 = 0.11), and 25.6% for the beliefs (ηp2 = 0.14) scores from baseline to 6 months' follow-up assessments among the intervention group (p < 0.001). The results also showed a significant interaction effect between group and time. CONCLUSION: The T-Bak intervention was effective in improving back-related behavior in pupils. It is now available and could be evaluated further in back-care related studies.

Educational needs assessment among 10-14-year-old girls about puberty adolescent health of Ardebil.

BACKGROUND: This study aimed to investigate the educational needs of 10-14-year-old girls about adolescent puberty health in Ardabil City in Iran, the matter of adolescent puberty health is one of the most important health priorities, especially for girls. METHODS: This cross-sectional descriptive-correlational study was performed on girl students through stratified-cluster sampling in Ardabil city. The data gathering tool was a self-reported researcher-designed questionnaire consisting of 10 demographic questions and 35 self-care questions in 5 domains of self-care awareness, self-efficacy, enablers, enhancers and behaviors, based on the reviewed articles and resources. Descriptive statistics and chi-square test, correlation coefficient and regression were used to analyze the quantitative data. RESULTS: The mean age of the girls was 12.98 ± 4.67. There was a significant relationship between the mother's level of education (p < 0.001) and students 'knowledge about puberty and between mother's age (p < 0.002) and students' awareness of self-care behaviors during adolescence. The results of this study showed that 73.8% of girls were aware of puberty and menstruation problems. About 74.3% of girls had poor self-efficacy. About 77% of female students in the study did not have access to the required educational resources and classes that are one of the most important enablers of behavior formation. Eighty-eight percent of the families did not talk about the hygiene practices related to their children. The most common source of information about maternal health related practices was from mothers (64.8%). Correlation test between adolescents' health behavior and awareness (r = 0.12 p < 0.007) and between self-efficacy and health behaviors (r = 0.14, p < 0.001) revealed significant and positive relationships. CONCLUSION: There is a need among adolescent girls for information about adolescent health and related health behaviors. Currently there is lack of adequate and accurate information. The role of mothers is the most important source of information for adolescent girls and educational approaches for mothers and adolescents should be designed.

Designing and psychometric evaluation of Stretching Exercise Influencing Scale (SEIS).

OBJECTIVE: The lack of reliable and valid tools for assessing the factors that influence stretching exercises (SEs) among Iranian office employees is obvious. This study aimed to design and evaluate psychometric properties of this instrument. DESIGN: Cross-sectional study of psychometric properties. SETTING: Data were gathered from May to September 2017. PARTICIPANTS: Participants were 420 office employees who were working in 10 health centres affiliated to the Shahid Beheshti University of Medical Sciences in Tehran, Iran. PRIMARY OUTCOME MEASURES: The instrument was designed on the basis of the constructs of the health promotion model (HPM) and extant literature. Exploratory factor analysis (EFA), Cronbach's α and intraclass correlation coefficient (ICC) were employed to check the scale's psychometric properties. RESULTS: In total, 420 questionnaires were completed. The mean age of the office employees was 37.1±8.03 years. Among the 86 items, 77 items had significant item-to-total correlations (p<0.05). The results showed good internal consistency and reliability for the whole questionnaire and each domain. EFA results confirmed 53.32% of the total variance of the items yielded in 11 subscales. The ICC was acceptable (0.78, 95% CI 0.70 to 0.88). CONCLUSIONS: The Stretching Exercise Influencing Scale (SEIS) can be a reliable and valid instrument for measuring the factors that influence SEs among office employees.

Risk-taking behaviors among motorcyclists in middle east countries: a case of islamic republic of Iran.

OBJECTIVE: Injuries caused by motor vehicle crashes in Middle Eastern countries are among the highest in the world. In Iran, road traffic crashes are the second most common cause of mortality. Particularly, motorcycle-related injuries among men are the second most common type of traffic-related crash in this country. This study used qualitative research methods to elicit and explore the personal experiences of Iranian motorcyclists in respect to factors that facilitate their engagement in risk-taking behaviors within the PRECEDE (predisposing, reinforcing, and enabling constructs in educational diagnosis, and evaluation) framework. METHODS: Focus groups, in-depth interviews, and field observation were conducted among motorcyclists, pillion passengers, and police officers. RESULTS: Our data show that being young and single, living in lower socioeconomic conditions, and suffering from poor physical health and daily stress influence risk-taking behaviors. Additionally, lack of defined traffic rules and regulations, the availability and accessibility of motorcycles among unlicensed underaged persons, the cost-effectiveness of motorcycle transportation, unsafe roads and a lack of special pathways for motorcycles, and aggressive car and van/truck drivers are among the enabling factors that provoke risk-taking behavior. Finally, the participants verified that the enjoyment of motorcycling reinforced their decision to continue engaging in risky behaviors, and being penalized for disobeying traffic laws prevented them from further risk-taking behaviors. CONCLUSION: Enabling and reinforcing factors to reduce risk-taking behaviors among motorcyclist could include (1) promoting smart driving practices among motorcyclists; (2) training pediatricians and emergency physicians to deliver brief motivational interventions to their young patients to avoid risky behaviors while riding; (3) training traffic enforcement officers to appreciate the value of providing consistent law enforcement services; (4) enhancing local efforts to increase the number of pathways for motorcyclists and improve the condition of deteriorated roads; (5) revising legislation and policies in association with motorcycle ownership among underaged and unlicensed individuals; (6) limiting an excessive number of passengers (particularly children) and cargo on motorcycles; and (7) identifying solutions to reduce the negative attitudes of car drivers toward motorcyclists and increase systematic compliance of traffic laws by motorcyclists and car drivers.

Consumption of fruit and vegetables among elderly people: a cross sectional study from Iran.

BACKGROUND: There is substantial evidence that low consumption of fruit and vegetables (FV) is a major risk factor for many chronic diseases. The aim of this study was to assess FV consumption and the variables that influence it among elderly individuals in Iran aged 60 and over. METHODS: This was a cross-sectional study to investigate FV intake by a randomly-selected sample of members of elderly centers in Tehran, Iran. A multidimensional questionnaire was used to collect data on demographic characteristics, daily consumption of FV, knowledge, self-efficacy, social support, perceived benefits, and barriers against FV. Data were analyzed using t-tests, one way analysis of variance, Pearson correlation, and logistic regression. RESULTS: In total, 400 elderly individuals took part in the study. The mean age of the participants was 64.07 (SD = 4.49) years, and most were female (74.5%). The mean number of FV servings per day was 1.76 (SD = 1.15). Ninety-seven percent of participants (n = 388) did not know the recommended intake was at least five servings of FV per day. Similarly, 88.3% (n = 353) did not know the size of a single serving. The most frequent perceived benefits of and barriers against FV consumption were availability and expense, respectively. Knowledge (OR = 0.59, 95% CI = 0.39-0.88), perceived benefits (OR = 0.92, 95% CI = 0.88-0.96) and barriers (OR = 1.08, 95% CI = 1.04-1.14), self-efficacy (OR = 0.89, 95% CI = 0.83-0.95) and family support (OR = 0.91, 95% CI = 0.83-0.99) were significantly associated with fruit and vegetable consumption. CONCLUSION: The findings of this study indicate that FV intake among elderly individuals in Iran was lower than the recommended minimum of five daily servings and varied greatly with age, marital status, educational attainment, and income level. The results also indicated that low perceived benefits, low self-efficacy, and perceived barriers could lead to lower consumption of FV. It seems that in order to improve FV consumption among elderly individuals in Iran, raising awareness, improving perception of benefits and enhancing self-efficacy regarding FV consumption should receive more attention. Indeed, it is essential to plan health education programs and nutritional interventions for this group of the population.

Correlates of low birth weight in term pregnancies: a retrospective study from Iran.

BACKGROUND: Low birth weight (LBW) is considered as a major multifaceted public health concern. Seventy-two percent of LBW infants are born in Asia. An estimation of 8% LBW infants has been reported for Eastern Mediterranean region including Iran. This study investigated contributory factors of LBW in singleton term births in Tehran, Iran. Tehran is a multicultural metropolitan area and a sample from the general population in Tehran could be regarded as a representative sample of urban population in Iran. METHODS: This was a retrospective study using data from 15 university maternity hospitals in Tehran, Iran. Data on all singleton term births in these hospitals were extracted from case records during a one calendar year. Study variables included: maternal age, maternal educational level, history of LBW deliveries, history of preterm labor, cigarette smoking during pregnancy, number of parities, chronic diseases and residential area (Tehran versus suburbs of Tehran). In order to examine the relationship between LBW and demographic and reproductive variables the adjusted logistic regression analysis was performed. RESULTS: In all, data for 3734 term pregnancies were extracted. The mean age of women was 25.7 (SD = 5.3) years and 5.2% of term births were LBW. In addition to association between LBW and maternal age, significant risk factors for LBW were: history of LBW deliveries [adjusted odds ratio (OR) = 2.53, 95% confidence interval (CI) = 1.06-6.03], smoking during pregnancy (OR = 4.64, 95% CI = 1.97-10.95) and chronic diseases (OR for hypertension = 3.70, 95% CI = 2.25-6.06, OR for others = 2.04, 95% CI = 1.09-3.83). CONCLUSION: The findings indicate that in addition to maternal age, history of LBW deliveries; smoking during pregnancy and chronic diseases are significant determinants of LBW in this population. This is consistent with national and international findings indicating that maternal variables and risk behaviors during pregnancy play important roles on LBW.
