ABSTRACT
BACKGROUND: Nutritional status during pregnancy can have a significant impact on infant and maternal health outcomes. To maintain maternal homeostasis and support fetal growth, adequate macronutrient and energy intake during pregnancy is essential. Therefore, this study sought to systematically review and meta-analyze macronutrient and energy intakes during pregnancy. METHODS: A systematic review and meta-analysis was carried out based on the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. The required data were collected from four databases including: Web of Sciences, ProQuest, Scopus, and PubMed, from 1 January 1980 to 30 May 2023, by using a combination of search terms (dietary pattern" OR "diet quality" OR "food habits" OR "nutrition surveys" OR "diet surveys" OR "food-frequency questionnaire" OR "diet record" OR "dietary recall") AND ( "pregnancy" OR "reproduction" OR "maternal health" OR "neonatal outcomes") among interventional and observational studies. Excel and STATA version 11 were used for data analysis. RESULTS: Among 7081 published articles, 54 studies were included in the review. Most of the 33 (61%) studies were cohort studies and a total of 135,566 pregnant women were included. The overall average of energy, carbohydrate, fat, and protein intake was 2036.10 kcal/day, 262.17 gr/day, 74.17 gr/day, and 78.21 gr/day, respectively. Also, energy intake during pregnancy was higher in American (2228.31 kcal/day, CI95%: 2135.06-2325.63) and Eastern Mediterranean regions (2226.70 kcal/day, CI95%: 2077.23-2386.92) than other regions (P < 0.001). Energy intake was higher in the third trimester than others (2115.64 kcal/day, CI95%: 1974.15-2267.27). Furthermore, based on the findings, there was a significant difference between energy intake in different World Health Organization (WHO) regions (P < 0.05). CONCLUSIONS: According to the results of meta-analysis, the average total energy was below than average total energy required during pregnancy. More efforts are needed to encourage women to adopt healthy eating habits during pregnancy to support healthy fetal and infant development.
ABSTRACT
Background: Infertility is a growing social problem, and health literacy is one of the factors that affects infertility, thereby affecting life quality. On the other hand, lifestyle factors exert a considerable impact on reproductive capacity and general health. Against this backdrop, this study aims to determine health literacy, general health, and lifestyle in infertile people in Zahedan, Iran. Methods: In this descriptive cross-sectional study, 86 male and 181 female participants who referred to Molod Infertility center (AliIbnAbiTalib Hospital) in Zahedan were randomly selected. Health Literacy Standard Questionnaires (HELIA), the General Health Questionnaire (GHQ), and the Miller-Smith Lifestyle Assessment Inventory (LSI) were used to collect data. In addition, data were analyzed by SPSS V.22. Results: The participants' mean age was 30.87±7.5. Besides, 39% and 70% of the participations did not have enough health literacy and had a moderate lifestyle, respectively. In addition, the general health of 68.9% was exposed to damage. Moreover, there was a significant relationship between the three aforementioned factors, with the participants of higher levels of health literacy having had higher levels of general health and lifestyle. Conclusion: According to the findings of this study, the infertile people's health literacy was not enough, and most of them had a moderate lifestyle. In addition, their general health was exposed to damage in most cases. Thus, it is necessary to pay attention to providing proper education and health services to infertile men and women to improve their level of health literacy and healthy fertility in order to support childbearing in the society.
