The present study revealed that most of the provided education in HHs was related to the fields of family planning, maternal and child health, and reproductive health. In recent years, the high rate of reduction in total fertility has been discussed, and new approaches are necessary in this area. Overall, studies on the efficacy of education for family planning seem inadequate (
15).
Reproductive health includes physical, mental, and social health, besides different aspects, processes, and functions of the reproductive system. It encompasses family planning services, HIV/AIDS and other sexually transmitted diseases, maternal and neonatal health, sexual violence (
16), and all aspects of human health from birth to death. The international conference on population and development (ICPD) in Egypt highlighted the need to promote reproductive health programs around the world (
17). Therefore, it seems that considering women’s health issues, it is necessary to increase the coverage of family planning. Some provinces, which have the highest rates of family planning, also have a total fertility of less than 2 children in Iran.
Another topic was rural environmental health, which was mostly discussed in the marginal cities of Southwest and Northwest of Iran near the Lake Urmia. It seems that the poor conditions of rural environmental health have prompted primary healthcare workers to provide more instructions for patients. The rural culture is changing towards consumerism, which in turn leads to the production of imperishable waste. On the other hand, the rural population is still oblivious to waste management and environmental health (
18). Although the exact content of these educational programs is not the focus of this study, it seems necessary to create an intersectional partnership in the area of rural environmental health education, as rural municipal administrators manage rural environmental health.
Another issue was related to zoonotic diseases, which are common in provinces, such as Isfahan (
19) and Yazd (
20). However, the prevalence in these provinces is much lower than the mean national rate. Previous studies have emphasized on the importance of education for coetaneous leishmaniasis (
21) in the endemic regions of Isfahan (
22). The healthcare system should determine whether the given education is in accordance with the recognized importance of diseases in the region or is inconsistent with the region’s priorities.
In case of intestinal diseases, more education was provided in rural HHs, perhaps since most education was provided in summer, when diarrheal and intestinal diseases, such as Eltor, are more common. Coronary heart disease (CHD) is the leading cause of mortality in Iran, comprising about 50% of all deaths (
23,
24). Other studies have focused on the increasing prevalence of metabolic syndrome and obesity in Iran and have proposed various interventional methods (
25,
26).
Although the mentioned diseases comprise the health priorities of Iran and less educated people (such as rural populations) are at a great risk of these diseases (
27), only a small part of HH training was dedicated to cardiovascular diseases and risk factors in our study. In rural populations of Alabama (USA), India, and Egypt, similar results have highlighted the need for education regarding the risk factors (
28-
30). The limited education may be related to the negligence of this issue as a priority for human forces, low capacity for the desired level of education, and lack of attention by the authorities.
In a study by Mooney LA and Franks AM, instructions about cardiovascular risk factors were accompanied by disease screening (
31). Since the prevalence of CHD is higher in men than women and the relationship between education and CHD risk factors varies according to gender (
32), different types of education and training are necessary for men and women.
Road accidents are the second leading cause of death in Iran (
33). In fact, the mortality rate is 10 times higher than the global mortality rate due to car accidents (
34). Moreover, mortality rate due to road injuries is higher than the average rates in other countries (
35). However, despite its great importance, limited instructions are provided in this area. The need for safety education and control of road accidents in Iran is reportedly similar to Pakistan (
36). It seems that intersectoral attempts at training in this area must be in collaboration with the police force, highway patrol, mass media, and ministry of health.
In a study conducted in Fars Province, Iran, 10.7% of all deaths were related to accidental injuries (unintentional injuries) in rural regions (
37). Therefore, special attention should be paid to the education of male drivers, accompanied by an injury surveillance system. Considering the target groups, it seems that besides mothers (with children < 5 years), pregnant women, and eligible women for family planning, particular attention should be paid to teenagers and their risky behaviors, as well as patients with chronic diseases, risk factors for chronic diseases, and men with high-risk jobs.
Self-care education should be considered in diseases, such as hypertension and diabetes. Iran is a country with diverse ethnicities, languages, and priorities (
38). Therefore, these differences and priorities, as well as people’s needs and beliefs, should be taken into consideration in the design of training programs in HHs.
Among the limitations of the present study, one can mention the absence of a detailed examination of the content, effectiveness, and efficiency of educational programs; lack of examination through the year is another shortcoming. However, a major strength of this study is the comprehensive and nation-wide review of health clinic education.
