Primary Tooth Decay Prevention Program in Children: Application of Intervention Mapping Approach.

Background: As the most common diseases globally, oral and dental diseases are closely related to people's behavior. The present study is aimed at developing a program to prevent primary teeth decay in children using the intervention mapping approach. Methods: This study protocol is aimed at using the intervention mapping approach as the planning framework. The study consists of six steps of intervention mapping, including needs assessment based on the relevant literature review, development of an objectives matrix for changing people's behaviors and environmental factors, program preparation, program implementation, and program evaluation to develop a family-centered program. Results: The use of the intervention mapping approach helped us identify the outcomes and functional objectives, develop an appropriate intervention program, and evaluate the program. Conclusions: The intervention mapping approach is an appropriate guide to developing a systematic and evidence-based program.

Mothers' role in promoting oral health in children aged 6 months to 1 year.

INTRODUCTION: It is essential for parents, and especially mothers, to become aware of the factors that affect oral health-promoting behaviors in children through behavior change theories. This study aimed to determine mothers' role in improving children's oral health based on the health belief model (HBM). METHODS: The population of this descriptive, analytical, cross-sectional study comprised 240 mothers in Ilam (Iran), selected via stratified random sampling. The data collection instrument was a self-report questionnaire with two sections, including seven demographic and contextual questions, four items for perceived severity, four items for perceived benefits, four items for perceived barriers, three items for cues to action, and five items for perceived self-efficacy. The data were analyzed in SPSS 21 by using descriptive and inferential statistics, including independent samples t-test, linear regression analysis, and Pearson correlation coefficient, at a significance level of 0.05. RESULTS: The participants aged 20-47 with a mean of 31.8 ± 5.67 years. The linear regression analysis indicated that the constructs of perceived severity (B = 0.073, P < 0.001), perceived benefits (B = 0.013, P < 0.001), perceived barriers (B = 0.111, P < 0.01), cues to action (B = 0.517, P < 0.001), and perceived self-efficacy (B = 0.292, P < 0.001) explained 55% of the variance of behavioral intention. CONCLUSION: With respect to the effects of perceived barriers and perceived severity on predicting oral health behaviors, effective outcomes can be achieved by emphasizing these two constructs in educational programs based on the HBM.

Family-Centered Social Cognitive Factors Preventing Primary Tooth Caries in Children Based on Intervention Mapping Approach.

BACKGROUND: Given the increasing prevalence of primary tooth caries in Iran and the importance of providing evidence- and theory-based family-centered prevention programs, the present study is aimed at determining the family-centered social cognitive factors preventing deciduous tooth caries among children using the intervention mapping protocol. METHODS: This cross-sectional study was performed on 240 Iranian mothers in Ilam who were randomly selected to participate in the study. The data were collected using a self-designed questionnaire including items on demographic information and social cognitive constructs (knowledge, attitude, perceived severity, perceived benefits, perceived barriers, practice guidance, perceived self-efficacy, behavior intention, subjective norms, and social norms). The questionnaire was completed by mothers, and the data were analyzed by performing one-way analysis of variance and linear regression. RESULTS: The results obtained from linear regression analysis showed that perceived self-efficacy (B = 0.295, p < 0.001), perceived barriers (B = 0.084, p < 0.028), practice guidance (B = 0.774, p < 0.001), and social norms (B = 0.137, p < 0.020) accounted for 71% of the behavioral intention variance and were the most important predictors for preventing primary tooth caries among children. CONCLUSION: The findings suggest that perceived self-efficacy, perceived barriers, practice guidance, and social norms are essential for developing family-centered programs to prevent primary tooth caries in children.

Inequality in Utilization of In-patients Health Services in Iran.

BACKGROUND: Health services for those in need. Inpatient care shows a more serious side of individual care and patients and their family members perceive a high level of stress and urge. We conducted this study to determine inequalities of in-patient health care utilization in Iranian people and to assess factors that influence utilization. METHODS: In each province, the sample was comprised of 380 urban and 380 rural households that were recruited by a systematic random sampling method. A total of 23,560 households, which included around 102,000 individuals were recruited. We used the questionnaire for data collection. Met admission need (MAN) was the main variable and was considered household assets for determining the economic status. We did all analyses using the STATA version 9.1. RESULTS: The rates of MAN for urban and rural areas were 83% and 81.3% respectively. The rate of MAN was significantly higher in patients with higher educational level. Patients with primary health insurance coverage had significantly higher rate of MAN. CONCLUSIONS: Meeting admission needs was estimated around 84% and it seems that modifying insurance coverage is the most feasible intervention for increasing utilization of health services.

Prevalence of General and Abdominal Obesity in a Nationally Representative Sample of Iranian Children and Adolescents: The CASPIAN-IV Study.

BACKGROUND: Pediatric obesity is one of the predisposing risk factors for many non-communicable diseases. OBJECTIVES: The purpose of this study was to estimate the national prevalence of general and abdominal obesity among Iranian children and adolescents. PATIENTS AND METHODS: This cross-sectional nation-wide study was performed in 30 provinces in Iran among 14880 school students aged 6 - 18 years, selected by multistage random cluster sampling. The World Health Organization growth curve was used to categorize Body Mass Index (BMI). Obesity was defined as BMI equal to or higher than the age- and gender-specific 95(th) percentile; abdominal obesity was considered as waist-to-height ratio of more than 0.5. RESULTS: Data of 13486 out of 14880 invited students were complete (response rate of 90.6%). They consisted of 6543 girls and 75.6% urban residents, and had a mean age of 12.45 (95% CI: 12.40 - 12.51) years. The prevalence rate of general and abdominal obesity was 11.89% (13.58% of boys vs. 10.15% of girls) and 19.12% (20.41% of boys vs. 17.79% of girls), respectively. The highest frequency of obesity was found in the middle school students (13.87% general and 20.84% abdominal obesity). The highest prevalence of general obesity was found in Boushehr (19%) followed by Guilan and Mazandaran (18.3%, 18.3%), while the lowest prevalence was observed in Hormozgan (2.6%). The highest frequency of abdominal obesity was found in Mazandaran (30.2%), Ardabil (29.2%) and Tehran (27.9%). Provinces such as Sistan-Baloochestan (8.4%), Hormozagan (7.4%), and Kerman (11.4%) had the lowest prevalence of abdominal obesity. The Southern and South Eastern provinces had the lowest prevalence of general obesity (2.6% and 5.6%) and abdominal obesity (7.4% and 8.8%). Moreover, the highest prevalence of obesity was found in North and North West Iran by maximum frequency of 18.3% general obesity and 30.2% of abdominal obesity. CONCLUSIONS: The results showed a high prevalence of general and abdominal obesity among boys living in the Northern provinces of Iran. The present study provides insights that policy makers should consider action-oriented interventions for prevention and control of childhood obesity at national and sub-national level.

Frequency, Causes, and Places of Unintentional Injuries in a Nationally Representative Sample of Iranian Children and Adolescents: The CASPIAN-IV Study.

BACKGROUND: This study aims to assess the frequency, causes, and places of injuries in a nationally representative sample of Iranian children and adolescents, as well as the referral, places allocated for injured individuals. METHODS: This nationwide study was conducted in 2011-2012 among 13486 elementary, secondary and high-school students who were selected by random cluster stratified multistage sampling from 30 provinces in Iran. The Global School-based Health Survey questionnaire of the World Health Organization was used. RESULTS: The study participants consisted of 50.8% boys, 75.6% urban resident with a mean age of 12.5 years. Overall, 20.25% of participants reported that they were minimally injured once in the last 12 months; this prevalence was higher in boys than in girls (25.74% vs. 14.58%, respectively, P < 0.001), without significant difference in urban (20.11%) and rural (20.69%) areas. Most of them (39.92%) were injured at homes or house yards with higher prevalence in girls than in boys (48.61% vs. 35.17%, respectively, P < 0.001) and in rural than in urban areas (27.30% vs. 20.89%, respectively, P < 0.001). Schools were reported as the second prevalent site of injury occurrence (22.50%). Emergency departments and physician offices were the most prevalent referral places for injured individuals (32.31% and 22.38%, respectively). Most of the school injuries occurred during play or sport activities (45.92%). CONCLUSIONS: Prevention of unintentional injuries should be considered as a health priority. Appropriate preventive strategies should be enhanced at homes and schools.

A Nationwide Survey on Some Hygienic Behaviors of Iranian Children and Adolescents: The CASPIAN-IV Study.

BACKGROUND: This study aims to assess the frequency of some hygienic behaviors that is, tooth brushing and hand-washing, in Iranian school students at national level. METHODS: This nationwide study was conducted in 2011-2012 among 14,880 elementary, secondary and high school students who were selected by random cluster stratified multistage sampling from 30 provinces in Iran. We used the global school-based health survey questionnaire of the World Health Organization. RESULTS: The population of this survey consisted of 13,486 children and adolescents (participation rate of 90.6%) including 49.2% girls and 75.6% urban inhabitants. The mean age of participants was 12.5 years (12.3-12.6, 95% confidence interval) According to the self-report of students, 26.9% of them (20.2% of boys and 33.9% of girls) brushed their teeth more than once a day, 37.8% of boys and 42.1% of girls brushed their teeth once a day. In general, girls brushed their teeth more than boys. The frequency of those students who never brushed their teeth was twice in rural than in urban students (11.4% vs. 6.2%, respectively). In total, 3.4% of the students stated that their school had not an appropriate place for washing hands after toilet, with three-fold higher frequency in rural than in urban schools (6.8% vs. 2.3%, respectively). 85% of students (87% of girls vs. 83% of boys) reported that they had always washed their hands after toilet, 10.1% did it occasionally and 4.1% did not. CONCLUSIONS: This nationwide survey revealed that Iranian students have an acceptable level of hygienic behaviors both in urban and rural areas; however, still it is necessary to improve school health facilities and hygienic habits in Iranian students.

Association of serum lead and mercury level with cardiometabolic risk factors and liver enzymes in a nationally representative sample of adolescents: the CASPIAN-III study.

This study aims to determine the difference of serum Pb and Hg levels in adolescents with or without metabolic syndrome (MetS) and the association of serum levels of these heavy metals with cardiometabolic risk factors and liver enzymes in Iranian adolescents. The study population consisted of 320 adolescents (160 with MetS and 160 healthy controls). The relationship between serum heavy metals and cardiometabolic risk factors was assessed by linear regression. The odds ratios (OR) of having metabolic syndrome across Pb and Hg quartiles were determined by multiple logistic regression analysis. The mean (SD) of Pb and Hg concentrations were higher in adolescents with MetS than in those without it (0.83 (0.27) and 0.17 (0.01) vs. 0.65 (0.15) and 0.10 (0.08) µg/L, P = 0.01 and 0.0001, respectively). Increase in serum Pb and Hg was associated with increase in some cardiometabolic risk factors. Among boys and girls, diastolic blood pressure (DBP), fasting blood glucose, total cholesterol (TC), triglycerides (TG), and alanine aminotransaminase increased significantly across quartiles of serum Pb. Among girls, SBP, DBP, TC, and TG had a significant increase across Hg quartiles. The corresponding figure among boys was significant for SBP, DBP, and TG. Higher quartiles of Pb increased the risk of having MetS (OR 95 % CI 3.10, 2.25-4.27), the corresponding figure was 2.03, 1.75-3.16, across Hg quartiles. Our study showed significant associations between serum Pb and Hg levels with cardiometabolic risk factors in adolescents. In future surveys, the role of potential confounders should be considered more extensively. The clinical significance of these findings needs to be confirmed in longitudinal studies. By considering the origins of chronic diseases from early life, controlling environmental pollutants should be considered as a health priority for primordial or primary prevention of noncommunicable diseases.
