Gaining weight above the Institute of Medicine recommended range contributes to the development of obesity, which increases risk for diseases. We evaluated the effectiveness of an educational program with the spouse's participation on the optimal gestational weight gain (GWG) in pregnancy. We conducted a randomized controlled trial on 128 nulliparous women attending Najmieh Hospital--Antenatal Clinic based in Tehran-Iran. Participants randomly allocated into two groups of interventions and one control group. In group A, the women received education with their spouse's participation. In group B, the women received education without the participation of the spouses. In the control group, women received only routine prenatal care. Data were analysed by the ANOVA and Chi-square coefficient. The mean of the total GWG in the groups A and B was significantly lower than the control group (13.50 3.85, 13.55 3.20 and 15.53 4.20 kg, respectively, P > 0.05). The rate of optimal GWG in groups A and B was 1.97 and 1.77 times of the control group, respectively (P < 0.05). The percentage of non-optimal GWG significantly decreased (P < 0.05). Groups A and B were not significantly different indicating no effect of spousal presence.

Background: Pregnant women have poor knowledge of oral hygiene during pregnancy. One problem with the follow-up of dental caries in this group is zero accumulation in the decayed, missing, and filled teeth (DMFT) index, for which some models must be used to achieve valid results. The studied population may be heterogeneous in longitudinal studies, leading to biased estimates. We aimed to assess the impact of oral health education on dental caries in pregnant women using a suitable model in a longitudinal experimental study with heterogeneous random effects. Materials and Methods: This longitudinal, experimental research was carried out on pregnant women who visited medical centers in Tehran. The educational group (236 cases) received education for three sessions. The control group (200 cases) received only standard training. The DMFT index assessed oral and dental health at baseline, 6 months, and 24 months after delivery. The Chi-square test was used for comparing nominal variables and the Mann–Whitney U test for ordinal variables. The zero-inflated Poisson (ZIP) model was applied under heterogeneous and homogeneous random effects using R 4.2.1, SPSS 26, and SAS 9.4. The level of significance was set at 0.05. Results: Data from 436 women aged 15 years and older were analyzed. Zero accumulation in the DMFT was mainly related to the filled teeth (51%). The heterogeneous ZIP model fitted better to the data. On average, the intervention group exhibited a higher rate of change in filled teeth over time than the control group (P = 0.021). Conclusion: The proposed ZIP model is a suitable model for predicting filled teeth in pregnant women. An educational intervention during pregnancy can improve oral health in the long-term follow-up.

Objective (s): In a situation where the vaccine was not completely accurate and up-to-date against different strains of the virus in all people of the world, compliance with health guidelines was the main key to prevent transmission. But what is clear is that compliance with health protocols is not the same among all communities and depends on factors. This article examines the effects and attitudes of health protocols. Methods: This research was a descriptive-quantitative cross-sectional study, which was conducted among 385 students of Shahid Beheshti University of Medical Sciences, Iran in the last week of May 2022. Factors affecting the adherence to water hygiene behaviors due to covid-19 were investigated using a questionnaire and the results were analyzed and reported in ordinal regression with SPSS 25 software. Results: The ratio of the average score of compliance (19.08) from the total of eight health behaviors to the maximum score (25) was reported as 76%. It was reported that the score of awareness was very high, 94%, and the average score of attitude was about 75%. In the ordinal regression, it was found that having knowledge was not effective in following all health protocols and only two behaviors of avoiding attending gatherings and avoiding losing when meeting acquaintances showed a statistically significant relationship. In other words, with the increase of each score of awareness, the chance of having higher compliance scores in these two behaviors increased by about 1.5 times. On the other hand, the attitude score had a statistically significant relationship with most of the behaviors, except the compliance of coughing and sneezing into a handkerchief or the corner of the arm, and it had a positive simultaneous effect on the compliance of the behaviors. Conclusion: The high level of awareness among the studied community can partially indicate the effectiveness of interventions in increasing awareness, but the gap between awareness, attitude and behavior indicates the need to pay attention to other factors affecting attitude and behavior.
