- ItemThe Action Plan and Strategy Development for the Community Readiness Improvement for Tackling Childhood Obesity (CRITCO) Study(Brieflands, 2021-10-31) Mahdieh Niknam; Nasrin Omidvar; Parisa Amiri; Hassan Eini-Zinab; Naser KalantariBackground: Community Readiness Improvement for Tackling Childhood Obesity (CRITCO) study has been developed based on the community readiness model (CRM) to improve the readiness of targeted local communities from two diverse socioeconomic districts of Tehran for tackling childhood obesity (CO) of late primary school children (10 - 12 years of age). Objectives: This study aimed to describe the rationale and process of developing the fourth phase of CRITCO study by developing an intervention package. Methods: The readiness level data was used to analyze strengths, weaknesses, opportunities, and threats (SWOT) of four intervention sites to guide proper strategies in partnership with key community members. Then, the action plan was developed as a living document to guide a 6-month quasi-experimental community-based intervention around the six dimensions of CRM. Finally, the community engagement process, outcome, and evaluation process were explained. Results: The current report described the action plan and strategy development of the CRITCO study. Expectedly, this study can provide valuable information to guide the public health policymakers in planning and executing relevant interventions.
- ItemAssociation between Social and Demographic Factors with Feeding Methods in 3-6-Years-Old Children(Brieflands, 2013-03-31) Maryam Gholamalizadeh; Saeid Doaei; Naser Kalantari; Bahram RashidkhaniBackground : Healthy Nutrition has an important role in childhood. Food habits of a child probably will continue to adulthood and increase the risk of many chronic diseases. Role of parents in child nutrition as a food producer and eating pattern has recognized to most important factor of child nutrition. Recent studies have shown that the methods used by parents to child feeding have an important role in the child’s diet and BMI. This paper aimed to investigate which parents use which types of parenting control practices to manage their children’s nutrition. Materials and Methods : A cross-sectional survey of 208 parents with children aged 3-6 years was carried out in 30 primary schools. Measures included demographic and social factors and aspects of child feeding practices.Results : Results showed that stay at home mothers used more modeling practices. Mothers of sons used more pressure to eat than others. Older mothers used less pressure to eat. Mothers with higher BMI used more emotion regulation strategy and less modeling. And mothers with more education used more modeling.Conclusion : The results showed a significant relationship between demographic and social factors with aspects of the feeding practices.

- ItemCan Food Reformulation Policy Reduce Calorie Intake and Tackle Childhood Obesity?(Brieflands, 2020-12-31) Ali Milani Bonab; Naser Kalantari; Azizollah Zargaraan; Arezoo Haghighian Roudsari; Samira PourmoradianContext: Childhood obesity has become one of the most concerning public health issues and several innovative strategies are being applied to tackle the issue. Reformulation of children-oriented food products may play a role in improving childhood obesity. However, there is not sufficient evidence that shows the effectiveness of this policy. This paper provides a systematic review of the evidence to examine the efficacy of food product reformulation on calorie intake and weight modification of children with obesity. Evidence Acquisition: A comprehensive literature search was undertaken for different types of studies. PubMed, Cochrane Library Database, EMBASE and SCOPUS were referred to as the source of literature. Results: Seven thousand four hundred and three results were entered into our study for screening and evaluation. Our study showed that there was no clear evidence that supported the effectiveness of this intervention. However, some bodies of literature show calorie intake reduction, but no weight modification. Conclusions: Although there is enough evidence to show that reformulation may promote healthy dietary patterns, its impact on weight status is not convincing. Long term running intervention needs to be applied to examine the possible implications of food reformulation policy on the weight status of the children.
- ItemChitosan-Coated Alginate Microcapsules Loaded with Herbal galactagogue Extract: Formulation Optimization and Characterization(Brieflands, 2019-07-31) Nasim Khorshidian; Arash Mahboubi; Naser Kalantari; Hedayat Hosseini; Mojtaba Yousefi; Masoumeh Arab; Adriano Gomez da Cruz; Amir Mohammad Mortazavian; Fatemeh Sadat MahdaviMany herbs and spices have been recommended traditionally as galactagogues and several commercial formulations prepared using herbs. Due to the presence of various compounds such as polyphenols, flavonoids, isoflavones, and terpenes, bitter and stringent taste is elicited that make the consumption of these herbal preparations unpleasant. Moreover, these compounds are unstable when exposed to environmental conditions. In this regard, different approaches are used for taste masking such as microencapsulation. In the present study, microcapsules containing herbal galactagogue extract were developed through emulsification/external gelation and Box-Behnken design was used to investigate the effects of independent variables (sodium alginate: 1-1.5%, calcium chloride: 0.2-1% and extract concentrations: 1-5%) on encapsulation efficiency (EE%). Following evaluation of the model, the optimum condition of encapsulation process was selected as 1.49% sodium alginate, 0.84 CaCl2, and 1.58% extract with EE% of 77.97%. Microcapsules had an acceptable spherical morphology and the results of Fourier transform-infrared spectroscopy (FTIR) revealed the presence of the extract within the microcapsules. The mean diameters of the uncoated and chitosan-coated microcapsules were 52 and 123 μm and encapsulation yield was 50.21 and 69.7%, respectively. The polydispersity index of 0.45 and 0.48 were an indicative of polydisperse nature of the microcapsules. The loss of flavonoids in microcapsules stored at two different temperatures was insignificant. The in-vitro release in simulated gastric fluid (SGF; pH 1.2) and simulated intestinal fluid (SIF; pH 7.4) were 48.1% and 80.11%, respectively during 24 h. The prepared extract-loaded microcapsules have potential to be used in matrices with neutral pH.

- ItemAn Overview of Importance of Breastfeeding(Brieflands, 2014-05-01) Foad Alimoradi; Maryam Javadi; Ameneh Barikani; Naser Kalantari; Mohamad AhmadiContext: According to some studies, the tendency of mothers to breastfeed has declined in recent years. Due to numerous benefits of breastfeeding which had been reported, this problem may put children’s health and overall health of society at risk. In this study, we reviewed previous studies, emphasizing importance and necessity and enumerating benefits of breast-feeding. Evidence Acquisition: Databases including Science Direct, Biomed, Medline, Cochrane Library, EMBASE, SID, and magazines related to the topic were searched using keywords. Articles that examined various aspects of breastfeeding were analyzed as well. Results: The most perfect food for babies during the first two years of their lives is breast milk. It has so many health benefits for both mother and baby. Breastfeeding was studied from various aspects. There was significant correlation between the examined factors in vast majority of papers. However, some factors that researchers considered important did not give definitive results; therefore more extensive research is needed in this area. Conclusions: Breast milk is the most perfect food for babies during the first two years and no replacement is recommended during this time. Breastfeeding has so many health benefits for both mother and baby during the breastfeeding period as well as in the future.
- ItemPrevalence of Malnutrition Among Iran’s Under Five-Year-Old Children and the Related Factors: A Systematic Review and Meta-Analysis(Brieflands, 2018-02-28) Mohammad Mohseni; Aidin Aryankhesal; Naser KalantariContext: Children’s health is one of the priorities in most societies. Nevertheless, the highest prevalence rate of malnutrition occurs among under five-year-old children worldwide. Objectives: The aim of this study was to estimate the rate of malnutrition in Iranian children through a systematic review and meta-analysis. Also we tried to identify the most prevalent factors causing malnutrition. Data Sources: The required data were collected by searching the keywords of nutrition, malnutrition, under-nutrition, prevalence, epidemiology, etiology, occurrence and Iran in PubMed, Google Scholar, Scopus, Index Copernicus, DOAJ, EBSCO-CINAHL, SID, Magiran and Iranmedex. Results:: Twenty studies were selected for the final analysis stage, dating from 1999 to 2014. Number of children investigated for wasting, stunting and underweight was 53612, 54312 and 55012 respectively. The results showed that the prevalence of each type of malnutrition, in terms of wasting, stunting and underweight were 7.8% (95% CI: 4.8% - 12.6%), 12.4% (95% CI: 8.3% - 18.5%) and 10.5% (95% CI: 7.1% - 15.4%), respectively. Parents’ educational level, in particular mothers’, gender, birth weight, the place of residence, and mother’s occupation were mentioned as important factors causing malnutrition. Conclusion: The rate of malnutrition in Iran’s under five-year-old children is lower than the average of that in world and the Eastern Mediterranean region. Breastfeeding, the proper use of complementary feeding, and the principled spacing between births and improving the quality of maternal care have important role in prevention of malnutrition.
- ItemSleep Habits and Dietary Intake Among Preschool Children in Qazvin(Brieflands, 2014-02-01) Maryam Javadi; Naser Kalantari; Shabnam Jalilolghadr; Nasrin Omidvar; Bahram Rashidkhani; Parisa AmiriBackground: Sleep habits and total sleep duration are essential factors for healthy growth and development of children. There is evidence showing that eating time and quantity as well as proportion of foods macronutrients affect the sleep quality. Objectives: The aim of this study was to investigate the sleep habits of preschool children in Qazvin and the role of calorie, macronutrients and caffeine intake in a mixed normal meal on sleep induction. Materials and Methods: A total number of 210 children of 3 - 6 years old (108 boys and 102 girls) were randomly selected from a pediatric clinic in the city of Qazvin. Participants’ heights and their weights were recorded using standard techniques. Sleep habits questionnaires were filled out and three 24-hour diet-recalls for one weekend and two weekdays were assigned by a trained health worker. Results: The total night sleep duration, bedtime and wake-up time in the morning were 10.30 ± 1.30 hours, 23.30 ± 1.30 pm and 9.0 ± 1.30 am, respectively. Among all children, 21.9% had sleep onset latency and the bedtime of 56% was 10 pm or later. The results of this study showed no significant relationship between calorie, macronutrients, and caffeine intakes of the children, and the total sleep duration, bedtime, wake-up time, and sleep latency (P > 0.05). Conclusions: Based on the results of this study, no significant relationship was observed between the dietary intake and sleep habits. This might be due to the small sample size or other factors, suggested to be investigated in the future.
