Abstract

BACKGROUND

There is a conspicuous lack of knowledge, attitudes, and practices (KAP) studies directed towards understanding the impact of diet on pregnancy among infertile individuals. Dietary habits can have a certain impact on infertility. To investigates the KAP of infertile individuals regarding the influence of diet on pregnancy.

METHODS

A cross-sectional study was conducted from July 2023 to January 2024 in Beijing, China. A structured questionnaire based on comprehensive literature review and validated by expert consultation was administered to gather demographic information, as well as to assess KAP among individuals experiencing infertility. The Cronbach's α coefficient was 0.897, indicating high internal consistency. Statistical analyses included descriptive statistics, correlation analysis, logistic regression, and structural equation modeling.

RESULTS

A total of 580 participants were included in this study. Of these, 494 individuals (85.17%) were identified as female, while 325 participants (56.03%) reported experiencing infertility for a duration spanning 0 to 3 years. The mean knowledge, attitude, and practice scores were 27.04 ± 9.80 (possible range: 0-46), 21.84 ± 3.24 (possible range: 5-25), and 25.69 ± 4.07 (possible range: 9-45), respectively. Multivariate logistic regression showed that attitude score and aged more than 40 years were independently associated with proactive practice. The structural equation modeling (SEM) analysis revealed a significant direct influence of knowledge on both attitude and practice.

DISCUSSION

Given the identified gaps in knowledge and practice, healthcare providers should prioritize educational interventions targeting infertile individuals, particularly focusing on enhancing awareness and promoting proactive dietary practices to improve pregnancy outcomes.

CONCLUSION

Infertile individuals demonstrated insufficient knowledge, positive attitudes, and passive practices regarding the impact of diet on pregnancy.

摘要

背景

针对了解饮食对不孕不育人群妊娠影响的知识、态度和行为（KAP）研究明显不足。饮食习惯会对不孕不育产生一定影响。旨在调查不孕不育人群关于饮食对妊娠影响的KAP。

方法

于2023年7月至2024年1月在中国北京进行了一项横断面研究。采用基于全面文献综述并经专家咨询验证的结构化问卷，收集人口统计学信息，并评估不孕不育人群的KAP。克朗巴哈α系数为0.897，表明内部一致性较高。统计分析包括描述性统计、相关性分析、逻辑回归和结构方程模型。

结果

本研究共纳入580名参与者。其中，494人（85.17%）为女性，325名参与者（56.03%）报告不孕不育持续时间为0至3年。知识、态度和行为的平均得分分别为27.04±9.80（可能范围：0 - 46）、21.84±3.24（可能范围：5 - 25）和25.69±4.07（可能范围：9 - 45）。多因素逻辑回归显示，态度得分和年龄超过40岁与积极行为独立相关。结构方程模型（SEM）分析显示，知识对态度和行为均有显著的直接影响。
