Behzad Damari, Zahra Abdollahi, Mona Pourghaderi, Fatemeh Mohammadi-Nasrabadi
Int J Prev Med
2020, 11:173 (17 October 2020)
DOI
:10.4103/ijpvm.IJPVM_405_19
Background and Aims:
National Nutrition and Food Security Policy of Iran was developed and ordered by Office of Community Nutrition Improvement, in cooperation with National Nutrition and Food Technology Research Institute and National Institute of Health Research in 2012. This study was aimed at evaluating the success of the operationalization of the Policy between 2012 and 2015 and using the lessons learned in future policies.
Methods:
The participatory evaluation was conducted by taking part of all main partners including trustee organizations involved in implementation of the document, specialists and academic researchers, people's deputies, health service, headquarters experts at Ministry of Health. Three qualitative methods including reviewing evidences, interviews, and focus group discussions have been used to gather information. The degree of achievement of the document's strategic objectives, as well as the degree of adaptation of the document implementation to the desired state, has been determined.
Findings:
The mean percentage of progress in achieving outcomes and adaptation of the deployment method to ideal criteria (for 2016) of the National Document on Food and Nutrition Security from 2013 to 2017 are 52.6% and 41%, respectively. The best success was found in the existence of an evidence-based program (70%), a coalition of policy implementation (66.1%), and indicators for monitoring the progress of the document (61.1%). The least success was related to the weakness of public justification and public participation (20%) and lack of ranking and encouraging partners' function (24%). Lack of approval of the national document at the High Council for Health and Food Security of the country (HCHFS) was the important factor which led to less progress of the document.
Conclusion:
It is recommended to target avoiding structural changes while saving time, strengthening intersectoral capacity for collaboration, encouraging partners, and empowering the environment of the provinces in the coming years.

Vahid Sobhani, Mohammad Mehrtash, Hossein Shirvani, Mahdi Fasihi-Ramandi
Int J Prev Med
2020, 11:170 (5 October 2020)
DOI
:10.4103/ijpvm.IJPVM_64_19
Background:
Nowadays, the use of green tea supplements has increased. Studies have shown that green tea can have positive effects on anti-inflammatory and antioxidative factors, as well as improve aerobic performance capacity. Therefore, in this study, we investigate the effects of this supplement on inflammatory factors, total antioxidant capacity responses, and maximum oxygen uptake (VO
2
Max) of healthy young men in summer.
Methods:
This study is a double-blind randomized controlled trial (RCT) in which 15 young men (age 25.06 ± 2.1) were randomly assigned into the green tea (GT) and placebo groups. Subjects performed maximum aerobic exercises (shuttle run 20 m) in separate workouts (14 days) in summer. They consumed 640 mg green tea extracts or maltodextrin 90 min before exercise in a double-blind design. Blood samples were collected before and after the exercise and then evaluated in the biochemistry laboratory. In this study, one way analysis of variance (ANOVA) tests were used for the statistical analysis.
Results:
The results of this study show that green tea supplement significantly slowed down the increasing tumor necrosis factor alpha (TNF-α) (GT: 15.03 ± 4.31 [pg/ml], placebo: 31.38 ± 7.18 [pg/ml], [
P
= 0.000]); increased the total antioxidant capacity (GT: 1.04 ± 0.06 [mm], placebo group: 0.72 ± 0.04 [mm], [
P
= 0.001 VO
2
]); and Max (GT: 44.43 ± 3.06 [ml/kg/min], placebo group: 34.88 ± 1.30 [ml/kg/min], [
P
= 0.001]) in the supplement group than placebo. In addition, no significant differences in interleukin 1 beta (IL-1β) was observed between thee groups (GT: 26.86 ± 5.05 [pg/ml], placebo group: 23.47 ± 3.16 [pg/ml], [
P
= 0.251]).
Conclusions:
The consumption of green tea supplements 90 min before aerobic exercise may decrease inflammation and oxidative stress factors and improve VO
2
Max in summer.

Soraya Doustmohamadian, Sahar Mehrizi, Mohammad Naser Rahbar, Majid Mirmohammadkhani
Int J Prev Med
2020, 11:169 (5 October 2020)
DOI
:10.4103/ijpvm.IJPVM_254_19
Background:
Congenital hypothyroidism (CH) is an important and preventable cause of intellectual disability. This study determined the incidence of CH and its related factors in Semnan city in Iran.
Methods:
All neonates born in Semnan from 2011 to 2016 who participated in a screening program for CH were evaluated to estimate the incidence of CH. In a nested case-control study, all diagnosed CH cases were compared with a control group of healthy newborns. Statistical analysis used conditional logistic regression model with STATA-14.
Results:
106 out of 17,507 neonates born in Semnan during 2011–2016 were diagnosed with CH (6.05 cases per 1,000 live births). Maternal parity (odds ratio [OR] =1.78,
P
= 0.044), birth weight (OR = 0.29,
P
= 0.001), parental history of thyroid disease (OR = 3.43,
P
= 0.001), father's education (OR = 0.71,
P
= 0.003), father's occupation (nonworker) (OR = 2.97,
P
= 0.001), and the presence of other anomalies (OR = 4.14,
P
= 0.037) were related to the incidence of CH.
Conclusions:
The cumulative incidence of CH in Semnan was higher than in both the global and national statistics. Aside from well-known medical determinants, some important social factors such as father's occupation and education have a significant and independent relationship with occurrence of CH; rational attention should be given to them in health care programs to increase the effectiveness of preventative measures for CH.

Vahid Rezai, Reza Mahdavi-Nejad, Vahid Zolaktaf
Int J Prev Med
2020, 11:168 (5 October 2020)
DOI
:10.4103/ijpvm.IJPVM_403_19
Background:
Chronic back pain is one of the most challenging medical problems worldwide that results in disability, physical problems, and high costs for the family and society. Therefore, it can be very beneficial to find an appropriate treatment with minimum side-effects for this disease. The present study attempted to compare the effects of different water gait protocols on the endurance and electrical activity of spine extensor muscles in men with nonspecific chronic back pain.
Methods:
The study adopted an experimental design in which 30 men with non-specific chronic back pain were selected through convenience sampling and using simple randomization method assigned into three groups of forward walking, backward walking, and sideways walking. Walking exercises were performed for 8 weeks, three sessions per week for 30 min. Twenty-four hours before and 48 h after the intervention, the endurance of spine extensor muscles and electrical activities were measured using the Ito test and electromyography, respectively. Data were analyzed in SPSS 23 using paired sample
t
-test and analysis of variance
. Results:
The results showed that backward walking in water significantly increases endurance and electromyography activities of spine extensor muscles (
P
< 0.05), while forward and sideways walking had no significant effect on these variables (
P
> 0.05). The results obtained from Bonferroni post-hoc test showed a significant difference between the strength of trunk extensor muscles and EMG of spinal cord extensor muscles in forward and backward water gait groups (
P
= 0.001, 0.006).
Conclusions:
According to the findings of this study, it seems that walking backward can be an effective therapeutic method for patients with chronic back pain.

Assessment of oxidative DNA damages in radiography staff via evaluation of its urinary biomarker (8-hydroxy2-deoxyguanosine)
Azam Salehi, Karim Ebrahimpour, Farhad Forouharmajd, Maryam Zarean
Int J Prev Med
2020, 11:164 (5 October 2020)
DOI
:10.4103/ijpvm.IJPVM_44_19
Background:
Studies have shown that one of the most important complications of exposure to ionizing radiation is the emergence of cancer tumors, as a result of oxidative DNA. Since different radiography groups have high rate of exposure to ionizing radiation, examining the susceptibility rate of cancer in these groups is of prime importance. Therefore, the present study was conducted to measure the level of 8-hydroxy2-deoxyguanosine(8-OHdG) in the radiographers' urine as a biomarker of oxidative damage while comparing it with the nonradiography staff.
Methods:
Samples of two groups were selected for this case-control study, wherein 35 subjects were selected from different radiography groups (including nuclear medicine, radiology, radiotherapy, and CT scan) while the other 35 subjects were staffs who had no exposure to radiation. Later, urine samples were collected at the end of the working shift to determine the 8-OHdG concentration. The samples were obtained via SPE (solid-phase extraction) method. Subsequently, the 8-OHdG concentration was measured by the GC-MS analyzer.
Results:
The results confirmed that, the average concentration of 8-OHdG in the radiographers' urine (253.4 ± 31.2 ng/mg of creatinine) had a significant difference as compared to the nonradiographers' urine (141.1 ± 21.9 ng/mg of creatinine) (
P
= 0.004).
Conclusions:
In conclusion, due to elimination of interfering factors, ionizing radiation affects the increase in 8-OHdG levels and acts as a potential biomarker for the damaged oxidative DNA.

Ashkan Yadollahi Farsani, Mehrbod Vakhshoori, Asieh Mansouri, Maryam Heidarpour, Farnoosh Nikouei, Mohammad Garakyaraghi, Nizal Sarrafzadegan, Davood Shafie
Int J Prev Med
2020, 11:163 (5 October 2020)
DOI
:10.4103/ijpvm.IJPVM_45_19
Background:
Hemoconcentration (HC) has been suggested to be a useful biomarker for determination of optimum diuretic therapy in acute heart failure (HF), but role of this factor in rehospitalization and death was still controversial. In this study, we aimed to define relation between HC and readmission and mortality rate among Iranian patients with acute HF.
Methods:
This was a prospective cohort study done from March 2017 to March 2018 using data of a HF section of Persian Registry Of cardioVascular diseasE. From a total number of 390 registered HF individuals aged 18 years or older, 69 ones showed alterations in hemoglobin (Hb) levels. Hb levels were measured at admission and discharge time. HC was defined as any increased level in Hb during hospitalization. The relation of HC with readmission and death rate was done using multiple logistic regression and Cox proportional hazard model, respectively.
Results:
The mean age of study population was 70.5 ± 11.9 years with the dominant percentage of male participants (66.9%). Patients showing HC during admission did not reveal any significant decreased likelihood of rehospitalization compared to negative ones. In comparison to HC negative patients, those showing increments in Hb levels had a borderline significant lower likelihood of mortality (hazard ratio: 0.82, 95% confidence interval, CI = 0.07–1.18,
P
= 0.08).
Conclusions:
Our data suggested that HC was associated marginally with reduced mortality rate 6 months post HF attack and could be utilized as a useful biomarker for risk stratification of HF patients. Several prospective longitudinal population-based studies are necessary proving these associations.

Sitanshu Sekahr Kar, Kalaiselvi Selvaraj, Gomathi Ramaswamy, KC Premarajan, Ganesh Kumar Saya, Vinodhkumar Kalidoss
Int J Prev Med
2020, 11:162 (5 October 2020)
DOI
:10.4103/ijpvm.IJPVM_6_19
Background:
Prehypertension increases the likelihood of hypertension, cardiovascular diseases, and renal failure, and it is amenable to control if it is detected early. The burden of prehypertension prevalent in the community is not much explored. This study aimed to estimate the prevalence and to identify the socio-behavioral and dietary factors related to prehypertension in South India.
Methods:
A community-based cross-sectional study was carried out where data related to socio-demographic status, substance use, dietary patterns, physical activity, and associated comorbidities were assessed using the WHO STEPwise survey tool. Adults aged >=18 years who were not previously diagnosed and treated for hypertension were assessed for prehypertension. Prevalence of prehypertension is reported as percentage with 95% CI. Association was reported as adjusted prevalence ratio obtained through multivariable log binomial regression adjusted for potential confounders.
Results:
Among 2399 participants, 2213 underwent screening. Among 2213 adults, 810 (36.6%, 95% CI: 34.6–38.6%) were in the prehypertension range. The adjusted prevalence for prehypertension was 36.2% among males and 37.2% among females, respectively. Being in the age group of 45–54 years aPR-1.36, body mass index (BMI) >23 Kg/m
2
aPR-1.25, consumption of more than 6 grams of salt per day aPR-1.15 times were more likely to be associated with prehypertension. The comorbid conditions such as diabetes are less likely to be associated with prehypertension aPR-0.54 (0.41–0.72).
Conclusions:
This community-based surveillance showed 36% of prehypertension among adults which would have been missed if we were to follow the routine cares such as opportunistic and high-risk-based screening. Since prehypertension increases the risk for various end organ failures, there is an impending need to focus on screening and promote healthy lifestyles.

DOI
:10.4103/ijpvm.IJPVM_247_18
Background:
Craving is one of the diagnostic criteria for nicotine dependence. The aim of this study was Translating and Validating of Tobacco Craving Questionnaire-Short Form (TCQ-SF) on Persian.
Methods:
Fifty smokers aged 15–65 years participated through a public invitation. The forward and backward translation was done according to Beaton's guideline, then all smokers completed questionnaire, in non-deprived and deprived states with a 1-week interval. After expert committee confirmed forward and backward translation, construct validity evaluated by confirmatory factor analysis (CFA), mean craving scores Independent sample T-tests between high and low Fagerstrom Test for Nicotine Dependent (FTND), and also, deprived and non-deprived smokers. The reliability assessment was done by Intraclass coefficient (ICC) and mean craving scores paired sample t test between two deprived states. The Cronbach's alpha was conducted for internal consistency.
Results:
The consensus Persian version of the questionnaire was obtained. The CFA indicated a significant (
P
< 0.001) association of four latent variables with questionnaire structure. The significant (
P
< 0.001) difference between craving scores in Independent sample t tests indicated the construct validity as concurrent validity. There was no significant difference (
P
= 0.063) between two deprived states' scores and ICC = 0.97, indicated questionnaire reliability. The Cronbach's alpha was 0.89, shows good internal consistency.
Conclusions:
The results confirmed the validity and reliability of the Persian version of the Tobacco Craving Questionnaire-Short Form.

Maryam Abshirini, Behzad Mahaki, Fariba Bagheri, Fereydoun Siassi, Fariba Koohdani, Mostafa Qorbani, Parvaneh Yavari, Gity Sotoudeh
Int J Prev Med
2020, 11:160 (5 October 2020)
DOI
:10.4103/ijpvm.IJPVM_243_18
Background:
The relationship between dietary fat quality (DFQ) indices and pre-diabetes has not been well studied. This study aimed to determine the association of DFQ indices and fatty acid intake with pre-diabetes.
Methods:
This case-control study included 150 subjects with normal fasting blood glucose (FBG) and 147 pre-diabetic subjects. Dietary intake was assessed by a validated food-frequency questionnaire. DFQ indices including atherogenicity (AI) and thrombogenicity (TI), the ratios of hypo- and hypercholesterolemic (h:H), polyunsaturated:saturated (P:S) and
n
-3:
n
-6 polyunsaturated fatty acids were calculated. FBG test and 2-hour oral glucose tolerance test (OGTT) were measured.
Results:
After adjustment for some confounding variables, a positive association was found between intake of total saturated fatty acids (SFA), myristic acid, palmitic acid, and pre-diabetes, and a negative association was observed among
n
-3 polyunsaturated fatty acids, eicosapentaenoic, docosahexaenoic and arachidonic acids intake and pre-diabetes. AI was found to be positively associated with pre-diabetes (OR 6.68, 95% CI 2.57-17.34). An inverse relationship was observed between
n
-3:
n
-6 (OR 0.37, 95% CI 0.14-0.93) and h:H (OR 0.20, 95% CI 0.07-0.52) ratios with pre-diabetes.
Conclusions:
Higher intake of dietary
n
-3 fatty acids was adversely, whereas SFA intake was positively related to pre-diabetes morbidity. DFQ indices may be a useful measure to investigate fat intakes and blood glucose disturbances.

Int J Prev Med
2020, 11:159 (5 October 2020)
DOI
:10.4103/ijpvm.IJPVM_203_19
Background:
The body image is a complex concept that influences various factors, one of these factors is the quality of life. The present study aimed to investigate the relationship between quality of life and body image perception in the medical students of Shahid Beheshti University of Medical Sciences.
Methods:
This descriptive study was carried out on 400 students of Shahid Beheshti University of Medical Sciences using a stratified random sampling method and the samples were selected from each faculty in 2017 using simple random sampling Questionnaires (PSDQ) and (SF-12) were used. Data were analyzed using mean and standard deviation and
t
-test, Mann-Whitney U, ANOVA, kelmogrouf smirnouf test and Spearman Correlation to SPSS 16 software and structural equation modeling (SEM) was to test the relationships between the three parameters (quality of life, body image, and demographic characteristics) using AMOS24 software.
Results:
The findings show Quality of life significantly correlated with two demographic variables: location and exercising of students. Body image perception significantly correlated merely with the body mass index and exercising. The Structural Equation Modeling (SEM) results confirmed a positive and direct relationship between the quality of life and body image perception.
Conclusions:
The results showed that there is a significant relationship between body image perception and quality of life. Therefore, by modifying and improving the students' quality of life in the dormitories, the level of students' self-concept can be raised in order to prevent the physical and psychological complications of this group of community.
