Key Takeaway
Note higher hospitalization rates for gynecological pathologies in mining districts; implications for targeted nursing interventions.

This retrospective cross-sectional study analyzed data from 4,935 gynecological inpatients treated at Jixi Jikuang Hospital in Heilongjiang Province, China. The population included patients with various uterine and ovarian diseases. The primary exposure was residence in mining-intensive districts compared to non-mining areas, with national averages serving as a comparator for disease proportions.

The majority of patients (60.7%) were aged 40–59 years, with the peak prevalence observed in the 40–49 age group (33.8%). The mean age was 47.2 ± 12.8 years. Uterine pathologies dominated the disease composition at 57.6%, while endometrial polyps accounted for 18.9% of cases, significantly higher than the national average of 14.5% (P < 0.05).

Hospitalization rates in mining-intensive districts ranged from 518.9 to 914.3 per 100,000, compared to 178.2 to 207.8 per 100,000 in non-mining areas. Most hospitalizations lasted 3–8 days, representing 66.2% of cases. No specific adverse events or discontinuations were reported in the safety data provided.

As a retrospective cross-sectional study, this research cannot establish causality. The findings imply implications for targeted nursing interventions but must be interpreted with caution regarding environmental exposures. Further research is needed to confirm these associations.

Imagine waking up to find a lump in your belly. You worry it is cancer. But it turns out to be a benign growth. This happens often in mining towns across Northeastern China.

Women in these regions face unique health challenges. A new look at hospital records shows a clear pattern. Most patients are between 40 and 59 years old.

The biggest problem is not cancer. It is non-cancerous issues like fibroids and polyps. These conditions cause pain and bleeding. They make daily life difficult.

Current treatments often focus on surgery. But many women want to avoid operations if possible. They need better ways to manage these common problems without losing their uterus.

The Surprising Shift

Doctors used to think all women had the same risks. They treated everyone the same way. But this study changes that view.

Here is the twist: women living near coal mines get sick more often. The rate of hospital visits is much higher there. In mining areas, nearly 1,000 women per 100,000 people get admitted. In other places, the number is less than 200.

What Scientists Didn't Expect

Why does this happen? The air and water in mining towns might be different. Chemicals from mining could affect hormone levels. This leads to growths in the womb.

Think of your body like a house. If the air quality is bad, the house gets dirty faster. Similarly, poor environmental conditions can trigger health issues. The body reacts by growing extra tissue.

The main culprits are uterine fibroids and polyps. Fibroids are like soft balls inside the uterus. They do not turn into cancer. But they press on organs and cause pain.

Polyps are small bumps on the lining. They can bleed during a period. Both conditions are common in this specific group of women. The environment seems to push them toward these issues.

Researchers looked at nearly 5,000 patients. They checked records from one major hospital. The data covered over four years. They compared local rates with national averages.

The goal was simple: find out what is different here. They wanted to help nurses care for these patients better.

The numbers tell a clear story. Over 60% of patients were middle-aged women. The top diagnosis was uterine pathologies. This includes fibroids and polyps.

These conditions made up more than half of all cases. Ovarian and cervical issues were also common. But the mining connection was the big surprise.

But there is a catch.

This does not mean every woman in the area will get sick. It means the risk is higher. The environment plays a role.

Doctors say this fits a bigger picture. Pollution and stress affect women's health everywhere. But mining towns face extra pressure.

Nurses need to know this. They can spot symptoms earlier. They can offer advice on lifestyle changes. This helps patients avoid surgery when possible.

If you live in a mining area, pay attention to your body. Watch for heavy periods or pelvic pain. Talk to your doctor about these symptoms.

Do not ignore them. Early care can prevent big problems later. You might need medication instead of an operation.

This study has limits. It only looked at one hospital. It did not test the air or water directly. We do not know exactly what causes the higher rates.

More research is needed. We need to prove the link between mining and these diseases.

Next steps include testing environmental samples. Scientists will look for specific chemicals. They will also study more women in different towns.

This research will take time. But it will lead to better care. Nurses will get new tools to help patients. Women will get answers to their questions.

PurposeThis study analyzed the epidemiological characteristics and distribution patterns of gynecological diseases among hospitalized patients in a tertiary hospital serving China's northeastern mining region, compared disease profiles with national averages, and discussed implications for targeted nursing interventions.MethodsA retrospective cross-sectional study was conducted using electronic medical records from 4,935 gynecological inpatients at Jixi Jikuang Hospital, Heilongjiang Province (January 2021–December 2025). Data collected included age, primary diagnosis (ICD-10 classification), residential district, insurance type, and length of stay. Regional hospitalization rates were calculated using Seventh National Census population data. Chi-square tests compared disease proportions with published national averages.ResultsAnalysis of 4,935 patients revealed distinct epidemiological patterns. The majority (60.7%) were aged 40–59 years, with peak prevalence observed in the 40–49 age group (33.8%; mean age 47.2 ± 12.8 years). Uterine pathologies dominated disease composition (57.6%), primarily endometrial polyps (18.9%) and uterine fibroids (18.6%), followed by ovarian diseases (15.9%) and cervical pathologies (13.5%). Geospatial analysis identified that hospitalization rates in mining-intensive districts (518.9–914.3 per 100,000) were higher compared with non-mining areas (178.2–207.8 per 100,000). Most hospitalizations lasted 3–8 days (66.2% of cases). Compared with national averages, significantly higher proportions were observed for endometrial polyps (18.9% vs. 14.5%, P
