Abstract
OBJECTIVES This study aimed to cross-culturally translate the Qualiveen-30 into Persian and validate it in Iranian patients with spinal cord injury (SCI) and multiple sclerosis (MS). METHODS This was a cross-sectional prospective validation study. The translation and cross-cultural adaptation of the original questionnaire was performed in accordance with published guidelines. A total of 154 patients with SCI or MS who suffered from lower urinary symptoms for at least 6 months were asked to complete the questionnaire in the first visit to the clinic and after 3 weeks. To assess reliability, the internal consistency was assessed by Cronbach's alpha coefficient, and validity was assessed using convergent and discriminant validities. RESULTS The Cronbach's alpha coefficients for the Qualiveen-30 at two assessments ranged from 0.82 to 0.95, indicating a good internal consistency for the questionnaire. There were high amounts of test-retest reliability for the Qualiveen questionnaire and each of its domains (ICC > 0.90). Also, Qualiveen and its domains had a moderate to high correlation with the International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form (ICIQ-UI SF) (0.36 < r < 0.57) and SF-12 MCS (-0.51 < r < -0.11) and SF-12 PCS (-0.29 < r < -0.19), indicating good convergent validity. Comparison of Qualiveen in groups of income, education and manner of voiding revealed the high discriminative power of this instrument. The hypothesized four factor structure was approved using confirmatory factor analysis (CFA). CONCLUSIONS In general, the Persian version of Qualiveen-30 performed is a reliable and valid measure for the evaluation of the quality of life related to lower urinary symptoms in patients with SCI or MS.

Abstract
OBJECTIVE Good personal hygiene (PH) behavior is recommended to prevent contagious diseases, and members of military forces may be at high risk for contracting contagious diseases. The aim of this study was to develop and test a new questionnaire on PH for soldiers. METHODS Participants were all male and from different military settings throughout Iran. Using a five-stage guideline, a panel of experts in the Persian language (Farsi) developed a 21-item self-administered questionnaire. Face and content validity of the first-draft items were assessed. The questionnaire was then translated and subsequently back-translated into English, and both the Farsi and English versions were tested in pilot studies. The consistency and stability of the questionnaire were tested using Cronbach's alpha and the test-retest strategy. The final scale was administered to a sample of 502 military personnel. Explanatory and confirmatory factor analyses evaluated the structure of the scale. Both the convergent and discriminative validity of the scale were also determined. RESULTS Cronbach's alpha coefficients were >0.85. Principal component analysis demonstrated a uni-dimensional structure that explained 59 % of the variance in PH behaviors. Confirmatory factor analysis indicated a good fit (goodness-of-fit index = 0.902; comparative fitness index = 0.923; root mean square error of approximation = 0.0085). CONCLUSIONS The results show that this new PH scale has solid psychometric properties for testing PH behaviors among an Iranian sample of military personnel. We conclude that this scale can be a useful tool for assessing PH behaviors in military personnel. Further research is needed to determine the scale's value in other countries and cultures.

Abstract
INTRODUCTION Several tools for the assessment of sexuality-related distress are now available. The Female Sexual Distress Scale (FSDS) and its revised version (FSDS-R) are extensively validated and among the most widely used tools to measure sexually related personal distress. AIM The aim of the study was to determine the psychometric properties of the Iranian version of the FSDS-R in a population sample of Iranian women. METHODS A total of 2,400 married and potentially sexually active women were recruited and categorized into three groups including (i) a healthy control group; (ii) a group of women with hypoactive sexual desire disorder (HSDD); and (iii) a group of women suffering from other female sexual dysfunction (FSD). Participants were asked to complete a set of questionnaires including the Iranian version of the Female Sexual Function Index (FSFI-IV), the FSDS-R, and the Hospital Anxiety and Depression Scale. MAIN OUTCOME MEASURES Sexuality-related distress and FSD as assessed by the Iranian version of the FSDS-R and the FSFI-IV are the main outcome measures. RESULTS Internal consistencies and test-retest reliability of the FSDS-R across the three assessments points for the three groups were >0.70. The FSDS-R correlated significantly with anxiety, depression, and the FSFI total score. Significant differences in the FSDS-R scores were found between healthy women, women with HSDD, and women with other types of FSD. Factor analysis of the FSDS-R yielded a single-factor model with an acceptable fit. CONCLUSIONS The Persian version of the FSDS-R is a valid and reliable instrument for the assessment of sexuality-related distress in Iranian women and can be used to screen patients with HSDD.

Abstract
The aim of the present study was to evaluate the psychometric properties of the measure among a sample of Iranian patients with bone metastases. One hundred and seventy-seven patients with bone metastases undergoing various treatments were recruited from Imam Khomeini Hospital in Tehran to participate in the study. The coefficient alpha affirmed internal consistency reliability of the Quality of Life Questionnaire for patients with Bone Metastases (QLQ-BM22). This measure discriminated well between subgroups of the patients based on performance status and responding to treatment. Confirmatory factor analysis confirmed the factorial validity of the four hypothesized QLQ-BM22 scales. Patients in this study had a similar interpretation of the items on the QLQ-BM22 regardless of gender. All scales of the QLQ-BM22 were sensitive to change after treatment over a month's follow-up, with the exception of psychosocial aspects. The Persian version of the EORTC QLQ-BM22 was highly reliable and is valid for use among patients with bone metastases who are undergoing various treatment regimes.

Abstract
This study aimed to examine the psychometric values of a Farsi-translated version of the International Index of Erectile Function among a population sample of Iranian men. A community sample of 2,345 healthy men and a clinical sample of 421 men with diagnosed erectile function from 2 cities of Iran participated in the study. Participants were asked to complete the International Index of Erectile Function, the Life Satisfaction questionnaire, and a demographic questionnaire at baseline. Four weeks later, both samples were asked to recomplete the International Index of Erectile Function. The response rates were 84% (n = 1,969) and 98% (n = 412) for healthy men and men with erectile function, respectively. The retest reliability of the International Index of Erectile Function showed excellent intraclass correlation coefficients for both the healthy and patient samples. The International Index of Erectile Function subscales correlated significantly with the scores resulting from the clinical rating of erectile function conducted by urologists. Men with erectile function, as diagnosed by urologists, had significant lower scores in all subscales. The results of the exploratory factor analysis indicated that the International Index of Erectile Function could be summarized into a 5-component solution.The Iranian version of the International Index of Erectile Function was found to be a highly valid and reliable instrument to be used for the assessment of erectile function in clinical and population samples.

Abstract
The aim of the present study was to investigate the psychometric properties of a translated and culturally adapted Iranian version of the Female Genital Self-Image Scale (FGSIS-I) in a sample of college women. Further, the relationship between women's self-image, body appreciation, sexual functioning, and gynecological exam behavior was explored. A sample of 1,877 female students from five different universities across Qazvin and Tehran completed the Female Sexual Function Index (FSFI), the Body Appreciation Scale (BAS), the Rosenberg Self-Esteem Scale (RSES), the FGSIS-I, and a gynecological exam behavior questionnaire. Good to excellent internal consistency reliability, test-retest reliability, and convergent and construct validity were found. Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) both provided a two-factor structure for the FGSIS-I. The validity of the FGSIS-I in predicting gynecological exam behavior of college women was tested using structural equation modeling (SEM). The final model accounted for 33% of the variance in gynecological exam behavior (p < 0.01). In conclusion, the FGSIS-I was found to be a highly valid and reliable instrument to assess female genital self-image in Iranian women.

Abstract
AIM The number of haemodialysis patients globally is increasing and spiritual resources may help overcome adjustment problems among such patients. This study examined the relationships between spiritual/religious, demographic and clinical variables and quality of life among Iranian Muslims undergoing haemodialysis. METHODS Using a cross-sectional design, 362 haemodialysis patients were surveyed from three general hospitals located in Tehran, Iran. Spiritual coping strategies, Duke University Religion Index, EQ-5D 3L and a demographic questionnaire were administered. Hierarchical regression was used to identify predictors of quality of life and health status. RESULTS The distribution of reported problems across dimensions of quality of life was: mobility (59.4%), usual activities (30.4%), self-care (21.3%), pain/discomfort (47.8%) and anxiety/depression (29.3%). Univariate analysis showed that factors such as age, sex, marital status, location, number of children, body mass index, serum albumin, having diabetes mellitus or other comorbidity, as well as spiritual/religious factors that were related to quality of life, health status or both. Regression models revealed that demographics, clinical variables and especially spiritual/religious factors explained about 40% of variance of quality of life and nearly 25% of the variance in health status. CONCLUSION Spiritual resources may contribute to better quality of life and health status among haemodialysis patients. Further longitudinal studies are needed to determine whether these associations are causal and the direction of effect.

Abstract
BACKGROUND AND AIM To evaluate the psychometric properties of the national Eye Institute refractive error correction quality of life questionnaire (NEI-RQL-42) among Iranian patients with refractive errors. MATERIALS AND METHODS Two samples of patients (n1 = 296, n2 = 95) were consecutively selected from the eye clinic of the Boo-Ali Hospital, Qazvin. A forward-backward procedure was conducted to translate and cross-culturally adapt the Iranian version of the NEI-RQL-42. A homogeneity, stability, and reliability test was conducted for the first sample after a two-week interval. Convergent validity was computed using the correlation between the NEI-RQL-42 subscale scores, National Eye Institute-Visual Functioning Questionnaire (NEI-VFQ-25), and the Short Form-36 (SF-36). Furthermore, Known-group analysis was performed, to determine the discriminant validity between the subgroups of patients with hyperopia, emmetropia, and myopia. Responsiveness to clinical change was tested by administering NEI-RQL-42 on the second sample that was scheduled for surgery. RESULTS Homogeneity was satisfactory with the Cronbach's alpha coefficients ranging between 0.70 and 0.92. The 13 subscales of the NEI-RQL-42 showed a considerable stability in intra-class-correlation (ICC) ranging between 0.70 and 0.89. Positive correlation coefficients were found among all subscales of the NEI-RQL-42 and the other quality-of-life instruments (NEI-VFQ-25 and SF-36). The NEI-VFQ-25 displayed excellent discriminant validity to differentiate the subgroups of patients, and was found to be responsive to change after the surgical correction at three months. CONCLUSIONS The Iranian version of the NEI-RQL-42 is a valid and reliable instrument to assess refractive error correction quality-of-life in Iranian patients. Moreover this questionnaire can be used to evaluate the effectiveness of interventions in patients with refractive errors.

Abstract
The aim of this study was translation and validation of the Duke University Religion Index in Iranian Muslims. The study was performed in two stages. In the first stage, 1,762 college students from Qazvin city with an average age of 21.2 years participated in the study. In the second phase, 796 college students with an average age of 23.7 were recruited from Tehran. A demographic questionnaire, Santa Clara Strength Faith questionnaire (SCSORF), and Duke Religion Index (DUREL) were administered. Cultural adaptation of these measures was performed by a forward-backward translation technique. Test-retest reliability and intraclass correlation coefficients (ICC) were used for assessing reliability. Convergent validity was measured by Spearman correlation between DUREL and SCSORF. Explanatory and confirmatory factor analyses (EFA and CFA) evaluated the factor structure. Results showed that the scale is reliable. Cronbach's alpha ranged from 0.866 to 0.921 and ICC ranged from 0.937 to 0.991. Correlations between DUREL and SCSORF were also strong (ranging from 0.62 to 0.79). Results obtained from CFA and EFA confirmed one-dimension for the DUREL. Thus, the DUREL appears to be a proper measure for assessing religiosity among Iranian Muslims. Further testing of the scale among minorities and those with special health-related conditions is suggested.

Abstract
INTRODUCTION.: Female sexual dysfunction has a known impact on the quality of life. AIM.: The purpose of this study was the translation and validation of an Iranian version of the Sexual Quality of Life questionnaire-Female (SQOL-F) in Iranian women. METHODS.: A population sample of N = 2,675 women aged 17-67 years from Qazvin City of Iran and two clinical population samples (women with sexual dysfunctions N = 295 and women with type 2 diabetes N = 449) participated in the study. A self-constructed demographic questionnaire, the SQOL-F, the Short Form Health Survey (SF-36), and the Female Sexual Function Index (FSFI) were used for data collection. MAIN OUTCOME MEASURES.: Internal consistency and test-retest reliability were examined. Correlations between the SQOL-F, SF-36, and FSFI were assessed with convergent validity. Furthermore, known-groups comparison analysis was conducted to compare differences in SQOL-F scores between healthy women and those with sexual problems and diabetes. Confirmatory factor analysis assessed the factor structure of the SQOL-F. RESULTS.: Cronbach's alpha ranged from 0.84 to 0.98. Significant correlations between the SQOL-F, SF-36, and FSFI scores were found (ranging from r = 0.4 to r = 0.72). The SQOL-F scores were significantly different between women with and without a clinical condition (P < 0.05). A unifactorial model provided the best fit to the data. CONCLUSION.: The questionnaire represents a suitable measure to assess sexuality-related quality of life to sexual function in healthy women, as well as in women suffering from a chronic medical condition. Application of the scale to other clinical samples needs to be further explored.

Abstract
The objective of the present study was to determine the reliability and validity of the Persian translation of the Pediatric Quality of Life Inventory (PedsQL™) 4.0 Generic Core Scales Young Adult Version in an Iranian sample of young adult patients with rheumatoid arthritis (RA). One hundred ninety-seven young adult patients with RA completed the 23-item PedsQL™ and the 36-item Short-Form Health Survey (SF-36). Disease activity based on Disease Activity Score 28 was also measured. Internal consistency and test-retest reliability, as well as construct, discriminant, and convergent validity, were tested. Confirmatory factor analysis (CFA) was used to verify the original factor structure of the PedsQL™. Also, responsiveness to change in PedsQL™ scores over time was assessed. Cronbach's alpha coefficients ranged from α = 0.82 to α = 0.91. Test-retest reproducibility was satisfactory for all scales and the total scale score. The PedsQL proved good convergent validity with the SF-36. The PedsQL distinguished well between young adult patients and healthy young adults and also RA groups with different comorbidities. The CFA did not confirm the original four-factor model, instead, analyses revealed a best-fitting five-factor model for the PedsQL™ Young Adult Version. Repeated measures analysis of variance indicated that the PedsQL scale scores for young adults increased significantly over time. The Persian translation of the PedsQL™ 4.0 Generic Core Scales Young Adult Version demonstrated good psychometric properties in young adult patients with RA and can be recommended for the use in RA research in Iran.

Abstract
OBJECTIVE To conduct an evaluation of an educational program based on the health promotion model (HPM) and stages of change to improve physical activity (PA) behavior among Iranian adolescents. METHODS This was a group randomized controlled trial with 165 participants in two groups (intervention/control). Data were collected using self-reported questionnaires based upon HPM constructs (benefits and barriers of action, self-efficacy, activity-related affect, interpersonal influences, and situational influences). The stages of change scale was used to select eligible participants (were placed on precontemplation, contemplation, or preparation stages) and to assess the trend. After collecting baseline data, the intervention was administered to the participants and follow-up data was collected 3 months after intervention. RESULTS In all, 88 males and 77 females with a mean age of 13.99±0.4 participated in the study. The differences in all HPM constructs, except activity-related affect and social influences, were significant (p < 0.01) between baseline and follow-up measurements. Adolescents in the intervention as compared to the control group were placed in action (70%) or preparation (30%) stages at follow-up. Multiple regression analysis revealed that competing preferences, social norms, role models, (p < 0.001), and commitment to action plan can significantly predict PA behavior. The model accounted for 22.5% of the variance in PA. CONCLUSIONS The results suggest that educational interventions based on stages of change can have important implications for improving PA among adolescents in more constructs of HPM.

Abstract
Parents and school staff play important roles in promoting children's oral health. Our study goals were to investigate whether an intervention targeting parents and school staff can improve the oral-health behavior and oral-health status of schoolchildren. Three-hundred and ninety-two schoolchildren in six schools in Tehran participated in a group randomized trial from September 2010 to March 2011. Schools were randomly allocated into three groups: comprehensive, student, and control. Intervention in the comprehensive group consisted of strategies to encourage children, their parents, and school staff to increase the frequency of toothbrushing and flossing. In the student group, the intervention targeted only children. The control group received no intervention. The primary outcome was change in oral-health behaviors (brushing and flossing), while the secondary outcomes were changes in oral hygiene and Community Periodontal indices and in Health Belief Model components. Multilevel modeling was employed for data analyses. Students who were in the comprehensive intervention group brushed and flossed significantly more frequently compared with those in the student intervention group. Although students' gingival health improved significantly in the comprehensive intervention group, such significant improvement was not seen in the student group. In conclusion, promising results are seen when the oral-health education targets both school and home settings.

Abstract
Background The aim of this study was to translate the EORTC quality of life questionnaire for brain cancer, the QLQ-BN20, into Persian, and to evaluate its psychometric properties when used among brain cancer patients in Iran. Methods A standard backward and forward translation procedure was used to generate the Persian language version of the QLQ-BN20. The QLQ-BN20 was administered together with the QLQ-C30 to 194 patients diagnosed with primary brain cancer. Multitrait scaling and confirmatory factor analysis (CFA) were used to evaluate the hypothesized scale structure of the questionnaire. Internal consistency reliability was estimated with Cronbach’s alpha. The ability of the QLQ-BN20 to distinguish between patient subgroups formed on the basis of performance status and cognitive status was evaluated, as was the responsiveness of the questionnaire to changes in performance status over time. Results Multitrait scaling and CFA results confirmed the hypothesized scale structure. The measurement model was consistent across men and women. Internal consistency reliability of the multi-item scales ranged from 0.74 to 0.89. The QLQ-BN20 distinguished clearly between patients with relatively good versus poor performance and cognitive status, and changes in scores over time reflected changes observed in performance status ratings. Conclusions These results support the validity and reliability of the QLQ-BN20 for use among Iranian patients diagnosed with primary brain cancer. Future studies should examine the psychometrics of the questionnaire when used in patients with brain metastasis.

Abstract
OBJECTIVE To describe the status of dental caries in a sample of Iranian adolescents aged 14 to 18 years in Qazvin, and to identify caries-related factors affecting this group. STUDY DESIGN Qazvin was divided into three zones according to socio-economic status. The sampling procedure used was a stratified cluster sampling technique; incorporating 3 stratified zones, for each of which a cluster of school children were recruited from randomly selected high schools. The adolescents agreed to participate in the study and to complete a questionnaire. Dental caries status was assessed in terms of decayed teeth (DT), filled teeth (FT) and decayed, missing and filled teeth (DMFT). A multivariate regression analysis was used to determine statistically significant associations between DMFT and other variables. RESULTS The study sample comprised 380 adolescents, 188 (49.5%) being male. The mean age of the adolescents was 15.42 (SD= 1.1) years, and the mean DMFT was 2.61 (SD=1.89). Boys had significantly higher DMFT scores than girls (P <0.05). The multivariate regression analyses revealed a significant relation between high DMFT scores and such variables as increasing age, male gender, lower levels of parental education, higher family income, lower frequency of tooth brushing and dental flossing, having a history of no visits to the dentist, and bad perception of own oral health. CONCLUSIONS The present study reveals that Iranian adolescents have a poor oral hygiene, as very few subjects brush and floss their teeth on a regular basis. Although the incidence of caries was found to be moderate, it was influenced by demographic factors such as age and gender in addition to socio-behavioral variables such as family income, the level of education attained by parents, the frequency of dental brushing and flossing, and both the frequency and type of visit to a dentist.

Abstract
OBJECTIVE The primary objective of the study was to translate and evaluate the psychometric properties of the Pediatric Quality of Life Inventory™ (PedsQL™) Oral Health Scale in over 1000 Iranian children. METHODS A standard forward and backward translation procedure was used to convert the US English dialect version of the PedsQL™ Oral Health Scale into the Iranian language (Persian). The Iranian version of the PedsQL™ Oral Health Scale, in combination with the PedsQL™ 4.0 Generic Core Scales, was then subsequently administered to 1053 Iranian children and 1026 parents. The reliability of the PedsQL™ Oral Health Scale was evaluated using internal consistency and test-retest methods. Known-groups discriminant validity, exploratory factor analysis (EFA) of the Oral Health and the four Generic Core Scales combined, and confirmatory factor analysis (CFA) of the Oral Health Scale alone were conducted. The Benjamini-Hochberg procedure was used to correct P-values for multiple comparisons. RESULTS Good to excellent internal consistency and test-retest reliabilities were demonstrated. The PedsQL™ Oral Health Scale demonstrated discriminant validity for subgroups of children across different decayed, missing and filled teeth (DMFT) index categories and gender. The EFA supported the a priori factor model of the combined five scales. The CFA analysis confirmed the unidimensional factor structure of the Oral Health Scale. CONCLUSIONS The PedsQL™ Oral Health Scale demonstrated excellent psychometric properties in combination with the PedsQL™ 4.0 Generic Core Scales. These five scales combined can be utilized to assess the multidimensional oral-health-related quality of life of Iranian children.

Abstract
OBJECTIVES To explore and describe attitudes towards tooth-brushing among Iranian adolescents. METHODS A series of focus-group sessions were held with 37 Iranian adolescents in schools. The groups comprised five to eight adolescents. All focus-group discussions were tape-recorded and then transcribed verbatim. All transcripts, codes and categories were read several times to extract a theme. Data were analysed using a qualitative content analysis approach. RESULTS Four major categories emerged from the analysis: brushing teeth is a necessary evil, parental influence on not brushing teeth, brushing teeth is insignificant, and brushing teeth is a health hazard. The theme identified in the latent content described that tooth-brushing is not part of the adolescents' activities of daily living. CONCLUSIONS Health educators should stress on the engagement of parents, awareness of the adolescents on brushing techniques and causes of toothache, and address any misconceptions regarding tooth-brushing.

Abstract
INTRODUCTION The aim of the study was to assess the validity and reliability of the SF-12 questionnaire in a sample of Iranian patients undergoing hemodialysis. MATERIALS AND METHODS One hundred and forty-four hemodialysis patients were included from dialysis centers in Zanjan, Iran, and were asked to complete the SF-12 and SF-36 questionnaires. An initial test-retest reliability evaluation was performed on a sample of 70 patients from the total group, with a retest interval of 14 days. Reliability was estimated by internal consistency and validity was assessed using known-group comparisons and construct validity on the patient group as a whole. A linear regression analysis was used to assess any variation in the physical component summary and mental component summary scores of the SF-36 with the respective component summary scores of the SF-12. In addition, the factor structure of the questionnaire was extracted by performing a confirmatory factor analysis. RESULTS Cronbach alpha for physical and mental component summaries were 0.89 and 0.90, respectively. The SF-12 showed a good discriminatory ability between subgroups of patients based on demographic and clinical variables. The confirmatory factor analysis for the original two-factor structure showed a good fit index (chi2 = 23.30, degrees of freedom = 13), goodness-of-fit index = 0.96, and root mean squared error of approximation = 0.079). CONCLUSIONS In general, the SF-12 has good psychometric properties and can be used as a shorter version of the SF-36 questionnaire in future studies involving Iranian patients undergoing hemodialysis.

Abstract
AIM The aims of the study were to translate the Kidney Disease Quality of Life--Short Form version 1.3 (KDQOL-SF ver. 1.3) questionnaire into Iranian (Farsi), and to then assess it in terms of validity and reliability on Iranian patients. METHODS The questionnaire was first translated into Farsi by two independent translators, and then subsequently translated back into English. After translation disparities had been reconciled, the final Iranian questionnaire was tested. An initial test-retest reliability evaluation was performed over a 10 day period on a sample of 20 patients recruited from a larger group (212 patients with end-stage renal disease on haemodialysis). Afterwards, reliability was estimated by internal consistency, and validity was assessed using known group comparisons and constructs for the patient group as a whole. Finally, the factor structure of the questionnaire was extracted by performing exploratory factor analysis. RESULTS All of the scales in the questionnaire showed good test-retest reliability (i.e. intraclass correlations between test and retest scores were >0.7). All of the scales met the minimal criteria (0.7) for internal consistency and Cronbach's-α ranged 0.71-0.93. Furthermore, results from a discriminate validity evaluation showed that the questionnaire could be used to discriminate between subgroups of the patients. Finally, a principal component analysis of the disease-specific scales indicated that this part of the questionnaire could be summarized into an 11 factor structure that jointly accounted for 79.81% of the variance. CONCLUSION The Iranian version of the KDQOL-SF questionnaire is both highly reliable and valid for use with Iranian patients on haemodialysis.

Abstract
OBJECTIVES To investigate mothers' awareness of their children's weight problem, and to evaluate the impact of an educational intervention on improving mothers' recognition of obesity in their children. METHODS Twelve primary schools from Tehran, Iran, were randomly chosen. Obese children were selected, and 300 mothers participated in the study. A questionnaire was completed by the mothers, who were then randomly divided into two groups. One group received education on obesity, whereas the other group did not receive any intervention. After 2 months, the same questionnaire was completed by both groups. A multiple logistic regression was performed. RESULTS Mother's pre-existing knowledge on obesity, their education and occupation, as well as family income, had significant effects on mothers' accuracy in identifying obesity in their children. The educational intervention significantly improved mothers' ability to identify obesity in their children compared with those without any intervention (OR = 15.23; 95%CI 5.95-38.96). CONCLUSIONS In Iran, a large proportion of mothers do not have general knowledge on healthy body weight for children, thus failing to recognize that their children are obese. Educational interventions could reduce the rate of such mistake and subsequently alter parental care.
