Understanding the Connection Between Lifestyle Factors and Infertility in Women: Insights from a National Health Study
Study Overview
Infertility is a pressing issue for many women around the globe, prompting extensive research into its causes. One notable study utilized the National Health Insurance Service (NHIS) database to explore the lifestyle factors and health outcomes associated with infertility in women. By leveraging this comprehensive data, researchers aimed to uncover how various lifestyle choices might influence the likelihood of infertility.
H2: Data Sources and Methodology
H3: Harnessing the Power of NHIS
The research harnessed the vast resources of the NHIS database. This invaluable data bank includes:
- Health insurance claims from medical institutions
- Comprehensive records from the General Healthcare Screening Program (GHSP)
- Information about enrollees, including health coverage types, contributions, and death records
The GHSP offers health screenings to all citizens aged 20 and older every two years. This program focuses on early diagnosis of various health conditions, including obesity, hypertension, diabetes, and other illnesses. The data collected under strict confidentiality guidelines provides a rich foundation for this pioneering research. Learn more about NHIS here.
H2: Defining the Study Groups
H3: Case vs. Control Groups
In this study, the case group comprised women diagnosed with infertility for the first time in 2020, while the control group consisted of women who gave birth in the same year. The researchers meticulously selected participants from women aged 20–49 as of 2018, focusing on cases that had reliable data from infertility-specific service codes introduced in 2017.
Infertility was classified based on medical visits or hospitalizations coded under ICD-10 (N97)—encompassing various types of infertility, such as anovulatory and tubal issues. Conversely, the control group consisted of women with no previous infertility diagnosis who experienced childbirth in 2020.

H3: A Closer Look at the Numbers
The study ultimately included 25,333 women diagnosed with infertility and 73,759 women who had given birth. To refine the analysis, researchers applied propensity score matching based on age, Charlson Comorbidity Index (CCI) scores, and income levels, ensuring balanced comparisons between both groups.
This comprehensive method led to a matched sample of 48,650 women, allowing for an in-depth examination of health behaviors and lifestyle habits.
H2: Risky Lifestyle Factors and Health Checkup Results
H3: Evaluating Lifestyle Choices
The research delved into several high-risk lifestyle factors using records from the GHSP (2018-2019). Some of these include:
- Drinking habits: Categorized into non/moderate or heavy drinking
- Smoking status: Differentiating between non-smokers, past, and current smokers
- Physical activity levels: Defined as moderate (≥3 times per week) or vigorous (≥once a week)
Health checkup results also revealed insights into body mass index (BMI), hypertension, diabetes, and other crucial health markers.
H2: Analyzing Additional Variables
H3: Impact of Socio-Demographic Factors
The study also considered several explanatory variables, including:
- Age groups (22–29, 30–34, etc.)
- Income levels across four quartiles
- Health insurance status
- Residential areas (capital vs. non-capital regions)
These factors played a significant role in understanding the broader context of women facing infertility challenges.
H2: Statistical Analysis and Findings
H3: Insights Through Comparative Analysis
Researchers employed a case-control study design, meticulously comparing the general characteristics of women with infertility against those who had given birth. Using statistical methods such as chi-squared tests and logistic regression, significant differences emerged in lifestyle risk factors, health outcomes, and menstrual disorders between the two groups.
Key findings indicated a correlation between unhealthy lifestyles and higher instances of infertility among women.
Conclusion: Bridging Lifestyle and Health
This pivotal study highlights the profound relationship between lifestyle factors and infertility in women, emphasizing the importance of healthy living. By raising awareness and fostering discussions around these issues, healthcare practitioners and individuals can work collectively toward improved reproductive health outcomes.
