Food security in communities can prevent health complications, so investigators have made efforts to find its related factors through various fields. This study aims to draw a road map for nutrition and food security research in Iran. 

Web of Science, PubMed, Scopus, Embase, and Islamic World Citation Center were searched for eligible publications in nutrition and food security related to Iran for the two decades from 2001 to 2020. Content analysis was done by a co-word network technique using VOSviewer software. 

Finally, 28,995 scientific publications among 50,444 search results were eligible to include in this study. The research map was drawn using 403,262 keywords obtained from the title and abstract of the papers. A 23.53% growth rate of publications was seen. Iranian articles were mainly published in scientific journals under 10 subject categories. The highly repeated keywords of "treatment", "plant", "age", "risk", and "consumption" were in publications. Moreover, the articles were categorized into thematic clusters of "environmental and climate change", "health ", "food industry and food safety", and "agriculture and water resources management" which were related to nutrition and food security. An increasing trend was observed in the number of publications during the past two decades in Iran. 

The relation of clinical nutrition, malnutrition, diet, and in recent years, food production and climate change with food security have been extensively studied by Iranian researchers. However, they have neglected studies on public health and policy in food and nutrition security, which reveals their dominant clinical or agricultural approach

The role of the mothers is very important in providing care and monitor their children`s health in general. Their awareness concerning quality of foods which is needed for each child`s developmental stage can effect on nutritional status This Study assess the effect of an nutritional education Program on mother knowledge regarding their children nutritional status.

Sixty moms were chosen from Al-Ayn Social Care Foundation International in Al-Samawah City and take on using a quasi-experimental design. The researcher used a non-probability "purposive sample" and measured the height and weight for child before calculating the body mass index.

The current study found a relationship between moms' educational level and knowledge regard to sociodemographic characteristics with a p-value of .001. However, there were no significant correlations observed between mothers' knowledge in the control group and their age, level of education, occupation, residency, monthly income, and sources of information.

Following the interventional program on nutrition-related health, the level of knowledge among the mothers in the study group was enhanced. The study suggested that the nutrition education program should be offered to all moms in order to enhance their understanding and enthusiasm regarding the significance of child nutrition. Additionally, it was advised that their education should be regularly updated.

Anxiety is one of the most prevalent mental illnesses globally. While there are long-established, separate, and bidirectional connections between nutrition, excess body weight, and anxiety, it is still unclear how these variables interact and affect anxiety state. The aim of the current investigation was to determine whether there was a significant interaction between major dietary patterns (DPs) and overweight/obesity status in relation to the chance of anxiety among Iranian individuals in Yazd, Iran.

This cross-sectional study was conducted on baseline data of a large Iranian cohort study (Yazd Health Study: YaHS-TAMYZ). Dietary intakes were collected via a validated food frequency questionnaire. Major DPs were identified by principal component analysis (PCA). Then, body weight was assessed via an accurate body analyzer. Anxiety score was also evaluated using the validated scale-21 (DASS-21) questionnaire. Finally, the interaction between DPs and overweight/obesity in relation to the odds of anxiety was assessed using a multivariable adjusted binary logistic regression.

In total, 5781 participants were included in the present investigation. Individuals with the highest adherence to "high animal protein" DP and with overweight/obesity state had significantly lower odds of anxiety compared to those with the lowest imitation and normal body weight (P for interaction: 0.03).

Findings of the current study revealed that the “high animal protein” DP may be inversely linked to the lower chance of anxiety in participants with overweight/obesity. Yet, further long-term prospective investigations are required to confirm the results.

As a modifiable risk factor, nutrition plays a pivotal role in the prevention or delay of oral squamous cell carcinoma (OSCC). This study was aimed to investigate and compare the dominant dietary patterns in the patients with and without OSCC.

This case-control study evaluated the usual dietary intake of 80 cases and 120 controls during 2019–2020 using the 117‑item Food Frequency Questionnaire, with confirmed validity and reliability. Factor analysis was used to detect the dominant dietary patterns. Data analysis was done by SPSS (version 21) using the Chi‑square test, ANOVA, logistic regression analysis, and independent t‑test (P < 0.05).

Three dietary patterns were identified, including the western dietary pattern, health dietary pattern, and traditional dietary pattern. The odds ratio (OR) = 1.181 and confidence interval (CI) = 0.671 and 2.082 were found for the western dietary pattern, OR = 1.087 and CI = 0.617 and 1.914 were detected for the healthy dietary pattern, and OR = 0.846 and CI = 0.480 and 1.491 were reported for the traditional dietary pattern. No significant difference was found between the study groups in the dietary pattern and the risk of disease. This relationship remained insignificant after adjustment for the energy intake and confounding factors.

There was no significant relationship between adherence to healthy, traditional, and western dietary patterns and OSCC. Consumption of vegetables and nuts had a protective role against the disease, but risky behaviors such as smoking and alcohol use were directly associated with the incidence of the disease.

The elderly population is projected to increase in Iran and the world. A large number of chronic diseases observed in the elderly could be prevented or treated by improving their lifestyle, including nutrition. The present study aimed to determine nutritional status and the affecting factors in the elderly in Gonbad Kavus, Iran. 

This descriptive-analytical study was performed on 139 elderlies aged more than 60 years who resided in Gonbad (northeast of Iran) in 2013. The subjects were selected via two-stage cluster sampling, and each health center was considered as a cluster. Data were collected using a demographic questionnaire and mini nutritional assessment (MNA) questionnaire. Moreover, anthropometric indices (e.g., weight and height) were measured using a fabric meter, stadiometer, and Seca scale. Data was analyzed in SPSS version 11.5 using Chi-square and ordinal logistic regression model. 

In total, 36% of the elderlies had a normal nutritional status, whereas 59% and 5% were at the risk of malnutrition and malnourished, respectively. Among the subgroups, the female elderlies (78.6%) and single participants (87.1%) were at the risk of malnutrition or malnourished. Gender was the only independent variable affecting malnutrition. In addition, malnutritional status and marital status were the only variables affecting the body mass index even in the presence of other variables. 

Based on the nutritional assessment of the elderly, special attention must be paid to elderly women with lower education levels and financial dependence. It is also recommended that periodic assessments be carried out in the elderly population using the MNA questionnaire.

Context: Effect of sexual relations on mental and physical health has been the concern of the Iranian physicians, over a thousand years ago. Sexual ethics is one of the specific health topics of Iranian medicine archives. From the Iranian medicine point of view, because of different mental and physical differences in human, their sexual power and need for sex is different. It is necessary to observe the normal range, since the sexual indulgence causes different illnesses. Evidence Acquisitions: In Iranian medicine, different variables such as time, location, mental and physical situation, and also various forms of sex are discussed in sexual health. Safe sex not just reduces many mental disorders, but also prevents many neurological, digestive, urinary and genital disorders. Also, sexual indulgence is most harmful for health and causes stiffness, weakness and different diseases; therefore observing moderation in sex, according to the therapeutic characteristics and power, has been emphasized.

To have safe sex, it is necessary to consider time, mental, and physical status. Having sex when the stomach is full impairs digestion. Sexual relationship after heavy sports and severe emotional reactions such as anger or sadness, and after diarrhea or blood sampling is harmful. It has been recommended that having sex in temperate weather, and after evacuation of urine and feces, considering necessary arrangements, make the couple reach orgasm. Also, in the Iranian traditional medicine references, specific nutritional and health recommendations have been proposed for the sexually active people.

Health care recommendations of Iranian physicians involve precious and new points for the updated scientific communities. Scientific revision of these recommendations can be promising for public health improvement..
