Association of Diastasis Recti with Abdominal Muscle Strength, Endurance, Postural Control, and Pelvic Girdle Pain in Postpartum Women

Erum Ghaffar — 2026-04-30

DRA or diastasis recti abdominis is a postpartum complication where the rectus abdominis muscles are separated, leading to impaired abdominal muscle function, reduced core stability, and functional limitations. However, its relationship with muscle strength, endurance, postural control, and pelvic girdle pain remains unclear. Objectives: To determine whether the severity of inter‑recti distance (IRD) within women already diagnosed with DRA is associated with abdominal muscle strength, endurance, postural control, and pelvic girdle pain in postpartum women. Methods: A total of 60 postpartum women with DRA were included. IRD was assessed using the fingerbreadth method. Abdominal muscle strength was measured through manual muscle testing (MMT), endurance by curl-up test, postural control using the Balance Error Scoring Scale (BESS), and pelvic girdle pain through the Pelvic Girdle Questionnaire (PGQ). Spearman correlation was applied to assess associations, and linear regression was used to identify predictors of IRD. Results: IRD showed a strong negative correlation with abdominal muscle strength (ρ = -0.938, p<0.001) and endurance (ρ = -0.970, p<0.001), and a moderate positive correlation with BESS score (ρ = 0.436, p=0.001). The relationship with PGQ was weak and not significant (ρ = 0.234, p=0.072). Mode of delivery was the only significant predictor of IRD (p<0.001). Conclusions: Increased IRD is associated with reduced abdominal strength, endurance, and impaired postural control, but not significantly with pelvic girdle pain. Mode of delivery is the only significant predictor of IRD.

Association between Iron Supplementation and Anemia among Pregnant and Postpartum Women in Pakistan: A Secondary Analysis of PDHS 2017–18

Manahl Imran — 2026-04-30

IDA and VAD during pregnancy and postpartum are important public health problems contributing to maternal and neonatal morbidity in LMICs. Coverage of supplementation is not consistent, and monitoring of uptake remains limited in developing countries despite WHO recommendations. Objectives: To determine the prevalence of anemia and its association with iron supplementation. Methods: A cross-sectional study was conducted on 100 pregnant and postpartum women using PDHS 2017–18 data. Anemia was considered hemoglobin < 11.0 g/dL. Iron supplementation uptake, postpartum Vitamin A supplementation, and 24-hour dietary recall data were obtained. Chi-square tests, independent-samples t-tests, and multivariate logistic regression were performed, with reporting of risk ratios (RR) and odds ratios (OR) with 95% confidence intervals. Results: The prevalence of anemia was 46%. Iron supplementation was received by 53% of women, and anemia was considerably higher among non-users (88.9%) compared with users (7.8%), with a significant association observed (p<0.001). Dietary diversity was also low, with only 31% consuming dark leafy green vegetables and 33% consuming Vitamin A-rich foods within the previous 24 hours. Iron supplementation remained significantly associated with lower odds of anemia in multivariate regression (OR = 0.03 p=0.015). Conclusions: Maternal anemia remains common despite the observed association between iron supplementation and lower anemia frequency. Strengthening supplementation delivery monitoring systems and community nutrition education may help address micronutrient deficiencies among pregnant and postpartum women.

Environmental and Geographical Determinants of Lung Cancer in Pakistan: A Growing Public Health Concern

Riffat Mehboob — 2026-04-30

Lung cancer is a cancer that starts in the cells in the lungs, which is often caused by smoking or exposure to air pollution. It is defined as the uncontrolled growth of cells. There are two main types: small cell lung cancer (SCLC) and non-small cell lung cancer (NSCLC) [1]. Early detection and treatment are key, but lung cancer is often diagnosed at advanced stages, which makes it challenging to treat effectively [2].

Lung cancer is a form of cancer with an incidence of 9,464 new cases in Pakistan (5.1% of all cancers). It is the third most common cancer. The mortality due to lung cancer is 8,307 deaths (7.0% of total cancer deaths). It continues to be a persistent disease with a 5-year prevalence of 12,805. The cumulative risk of developing lung cancer before the age of 75 is 0.69%. Lung cancer continues to increase in both males and females, especially in big cities like Karachi and Lahore [3].

The environmental determinants significantly influence the burden and geographical distribution of lung cancer in Pakistan. The combined effect of rapid urbanization, industrial growth, growing motorized transportation, and unsafe working conditions has led to a general increase in exposure to carcinogenic pollutants in both urban and rural areas. Furthermore, the vulnerability of high-risk communities is growing due to differences in environmental regulation and a lack of public knowledge of hazardous exposures.

Environmental exposure, such as industrial emissions, vehicle pollution, occupational risks, and indoor air pollution, is a primary factor contributing to this rise. Industrial activities and emissions from vehicle traffic are linked to the release of polycyclic aromatic hydrocarbons (PAHs), which can make people more susceptible to cancer, as noted by Rehman et al. [4]. They are common pollutants in urban air pollution and have a strong association with lung carcinogenesis. Likewise, Luqman et al. report that occupational exposure (elevated ORs 5.1 and 3.1) to pesticides and diesel exhaust is an important risk factor in agricultural workers [5]. Other environmental-lifestyle interactions that were reported were dietary patterns, especially high intake of red meat and chicken. The particulate matter exposure (PM2.5, PM10) in the Salt Range was high, as reported by Nasir et al. and is linked to the mortality of lung cancer, especially in adults over 30 years of age [6]. Abbas et al. also, through machine learning-based risk modelling, found that air pollution, tobacco smoke, benzene, and PAHs were the major environmental risk factors for lung cancer in major cities of Pakistan, such as Lahore, Karachi, and Islamabad [7]. The other key concern is indoor environmental exposure. Kausar et al. describe how biomass fuel use in rural households, including wood and coal burning, results in persistent levels of indoor air pollution and high exposures to particulate pollutants, which play a significant role in the burden of respiratory diseases, such as lung cancer [8].

Lung cancer in Pakistan demonstrates that the disease is strongly influenced by environmental carcinogens like outdoor air pollution, industrial pollution, occupational exposures, and indoor biomass fuel use, which have medical, environmental, and socioeconomic dimensions, and are associated with rapid urbanisation, industrialization, and household energy use. To conclude, a concerted and coordinated environmental health strategy is needed, with a focus on the need to regulate industrial and vehicle sources of emissions, increase occupational safety measures, and progressively move towards cleaner household fuels, as well as enhance air quality monitoring and environmental policy implementation in both urban and rural areas. Along with public health awareness campaigns and early screening programs, delayed diagnosis and poorer survival are also problems that must be addressed. The environmental burden associated with the incidence of lung cancer in Pakistan is ever-increasing and requires a concerted effort from healthcare authorities, environmental agencies, and policymakers.
