ABSTRACT
Background: Various indices have been used to estimate overweight and obesity; all have limitations and strengths. The prevalence of overweight and obesity may differ by ethnicity.
Aims: This study evaluated waist circumference [WC], waist-to-hip ratio [WHpR], waist-to-height ratio [WHtR] and neck circumference [NC] as reliable alternatives to body mass index for screening for overweight and obesity, and determined their optimum cut-off values in different ethnic groups.
Methods: The study was conducted from November 2015 to February 2016 among adolescents aged 1214 years from five ethnicities in the Islamic Republic of Iran: Arab, Kurdish, Sistani and Baluchi, Turkish and Turkman. Stratified multistage sampling was used to select 2444 students. Receiver operating characteristic curves were constructed to evaluate WC, WHpR, WHtR and NC as screening indices for overweight and obesity as categorized by body mass index centiles.
Results: The prevalence of overweight and obesity in the total sample were 15.3% and 9.2% respectively, with higher rates in students of Arab, Kurdish and Turkish ethnicity. The areas under curve ranged from 0.8 to 0.9 for WC, WHtR and NC. The mean optimum values with the highest sensitivity and specificity to identify overweight were: 72.3 cm [sensitivity 0.80, specificity 0.75] for WC, 0.46 [0.85, 0.70] for WHtR and 31 cm [0.76, 0.76] for NC. For obesity mean optimum values were: 77 cm [0.84, 0.81] for WC, 0.50 [0.84, 0.84] for WHtR and 31.5 cm [0.88, 0.71] for NC.
Conclusions: WC, WHtR and NC may be useful tools to screen for adiposity using their optimum values for sex and ethnicity

Introduction: Electronic health record is electronic data of [entire life of a person] registered by healthcare providers and shared in different health centers. The electronic health record has been announced to all medical universities of the country since 2015 by launching the Integrated Health System [SIB]. This study aimed to determine the satisfaction of urban family physicians and health care providers in Fars and Mazandaran provinces from SIB
Methods: This cross-sectional study was conducted in the winter of 2016 on urban family physicians and health care providers who were selected by systematic random sampling. Data collection tool was a researcher-made questionnaire consisting of 2 parts: demographic variables with 8 open and closed questions and satisfaction with 8 closed questions on Likert scale. The validity and reliability of the questionnaire were confirmed.
Results: The total number of 464 participants included 236 [50.9 percent] physicians and 228 [49.1 percent] health care providers. From these, 273[58.8 percent] were employed in Fars province and 191[41.2 percent] in Mazandaran province. The majority of participants [65.5 percent] were women. mean score of satisfaction of SIB [from 5 points] in general was 2.94+/-0.8, and it was 2.89+/-0.8 in the Fars and 3.03+/-0.7 in the Mazandaran provinces. Mean score of satisfaction was 2.75+/-0.7 in urban family physicians and 3.04+/-0.8 in health care providers. Satisfaction level showed significant difference based on participants' type of occupation [P=0.0001] and province [P=0.122]
Conclusion: The results showed that the satisfaction of employees was lower than the average level. It is recommended to redesign the structure of SIB more consistent with the needs of employees and with a user-oriented approach
