Faisalabad Initiative of Research and Management of NCDs

Background:

The burden of noncommunicable diseases (NCDs) continues to rise globally, and they have become the leading cause of morbidity and mortality, accounting for over 70% of deaths worldwide¹. Rapid lifestyle transitions and increasing urbanization have disproportionately affected low- and middle-income countries, which now bear a substantial share of the global NCD burden.

Pakistan, with a population of 241.5 million, is experiencing a double burden of both communicable diseases and NCDs¹³. The widespread adoption of sedentary lifestyles and unhealthy dietary patterns has contributed to a marked increase in NCDs across the country².

According to the WHO Hypertension profile 2025, it is the most prevalent NCD in Pakistan, affecting approximately 42% (41% males and 44% females) of the population¹¹, followed by diabetes, with a reported prevalence of 30.8%¹². Additionally, a recent cross-sectional study among adults attending a tertiary care hospital in Islamabad reported dyslipidemia in 71.6% of men and 78.4% of women, indicating a substantial underlying community burden³. Pakistan also ranks tenth among 188 countries in terms of overweight and obesity prevalence, with nearly half of its population classified as overweight or obese⁴. According to World Health Organization data, 58.1% of Pakistanis are overweight, and 43.9% fall within the obese category⁴.

Despite their profound public health and economic implications, efforts to address NCDs remain fragmented and insufficient.17 There remains a significant research gap in community-based NCD screening initiatives, particularly within the suburban and peri-urban communities of Faisalabad creating an unmet need to initiate a preventive strategy at community level to raise awareness about these diseases. This direction will minimize the increasing incidence and prevalence of NCDs and will ensure the quality health outcomes for better future.

Timely identification of these diseases through screening is a critical step in reducing their impact on individuals and societies. Early detection enables cost-effective management, improved patient outcomes and a higher quality of life.14 One of the most important ways of reducing deaths from noncommunicable diseases (NCDs) is to control the risk factors that lead to their development.6 In this context, the present study aims to evaluate a community-based project focusing on disease awareness, screening, and structured referral to trained treating physicians for early diagnosis and management of major NCDs. The findings are expected to inform scalable, evidence-based interventions to reduce NCD burden and improve population health outcomes in Pakistan.

Primary Objective: To determine the prevalence of obesity, diabetes, hypertension, and dyslipidemia (ODHD) in the suburban areas of Faisalabad through community-based health screenings.

Secondary Objective: To establish and pilot a formal referral pathway that connects newly diagnosed and/ or at-risk individuals from suburban Faisalabad to healthcare facility for confirmation of diagnosis and management and treatment adherence through periodic follow-up.

Methodology: This study will be a community-based cohort with a cross-sectional perspective involving creating awareness, screening for (ODHD) with follow-up of participants over a period of three months.

The study will be conducted in selected low-to-middle socioeconomic areas of Faisalabad, Pakistan, located in proximity to Faisalabad Medical Center (FMC).

Faisalabad Medical Center (FMC) will serve as the clinical and research site responsible for diagnostic confirmation, clinical evaluation, treatment initiation, follow-up assessments, and study data management under the supervision of the Principal Investigator.

Team Composition and Roles

Field Screening Team:

Community screening activities will be conducted by trained healthcare workers, supported by two field workers (1 male & 1 Female) and one field manager. The healthcare workers will be responsible for participant registration, informed consent, questionnaire administration, anthropometric measurements, blood pressure assessment, and point-of-care testing for blood glucose and cholesterol. The field workers will assist with community mobilization and on-site logistics.

The field manager will oversee daily screening activities, ensure adherence to study protocols, verify completeness and accuracy of collected data, and ensure timely referral of participants to Faisalabad Medical Center.

Clinical, Research, and Data Management Team:

The study will be conducted by a qualified physician and 2 research associates (1 male, 1 female). The physician will perform clinical evaluations, confirm diagnoses, and initiate treatment according to standard-of-care guidelines. The research associates will ensure participants' consent, questionnaire completion, facilitate physician's consultations, ensure completion of required laboratory investigations, participant follow-up and management, perform data entry and secure storage of study data and complete adverse drug reaction (ADR) forms during follow-up if any participant experiences medication-related side effects.

Data Storage, Confidentiality, and Access Control All paper-based study documents, including consent forms and screening questionnaires, will be stored in locked filing cabinets at Faisalabad Medical Center (FMC) under the supervision of the Principal Investigator. Electronic data will be entered into a password-protected and access-restricted database maintained on secure institutional computers at FMC.

Each participant will be assigned a unique study identification number. Identifiable information will be stored separately from study data in a password-protected linkage file accessible only to the Principal Investigator. All analyses will be conducted using de-identified (coded) datasets.

Access to identifiable data will be strictly limited to the Principal Investigator and designated authorized study personnel. Co-investigators and data analysts will have access only to coded or anonymized data. Incase needed the data will only be shared in encrypted form as permitted by the Principle Investigator. The study sponsor (Getz Pharma (Pvt) Limited) will not have access to identifiable or individual-level coded data and will only receive aggregated, anonymized results for reporting and regulatory purposes.

All study data will be retained securely for five years after study completion in accordance with institutional policies and ethical guidelines. Thereafter, paper records will be securely destroyed, and electronic data will be permanently deleted or stored in encrypted archives as per institutional requirements.

Quality Assurance and Confidentiality Daily review of completed forms will be performed by field manager for screening data and by principal investigator for post-diagnosis and treatment data to identify missing data or inconsistencies in dataset. All personnel will be trained in data confidentiality and participant privacy. Participants will be identified using unique study identification numbers, and access to identifiable data will be restricted to PI and authorized study staff only.

Sampling Methodology and Sampling Frame This study will utilize a community-based, consecutive sampling approach. Two suburban communities of Faisalabad will be purposively selected based on population density, accessibility, and limited access to structured NCD screening services. Within each community, temporary screening camps will be established, supported by a structured awareness and mobilization campaign involving local leaders, community volunteers, and informational outreach to encourage participation.

The sampling frame will include all adults (≥18 years) residing in the selected communities who attend the screening camps during the study period. Participants will be enrolled consecutively until the target sample size is achieved. This approach is appropriate for community health screening initiatives where individuals voluntarily self-present, and it allows efficient recruitment while ensuring broad community coverage. The final sample size of 3,000 participants (including 10% overestimation for attrition) will be distributed across the two communities.

Sample size

Sample size for the study has been calculated as per the prevalence of each disease. Below mentioned formula for sample size calculation is used:

N=(z2 * P * Q)/e2 N= Sample Size Z= Z-Score (1.96) P= Prevalence Q= Non-Prevalence e= Margin of error (5%)

Disease Prevalence % Sample Size Obesity[17] 58% 374 Diabetes[18] 31% 328 Hypertension[24] 43% 374 Dyslipidemia[19] 75% 288 Total sample 1364 (As two areas will be included, the total estimated sample size will be 2,728) Attrition rate 10% of total sample 273 Overall sample ≈ 3000

Statistical Analysis Plan Data will be entered, cleaned, and analyzed using statistical software SPSS v-22. Data will be checked for completeness, consistency, and outliers before performing the analysis. Continuous variables will be assessed for normality using graphical methods (histograms, Q-Q plots) and statistical tests where appropriate.

Descriptive Analysis Descriptive statistics will be used to summarize the study population. Continuous variables will be presented as mean ± standard deviation (SD) for normally distributed data, or median with interquartile range (IQR) for skewed data. Categorical variables will be summarized as frequencies and percentages.

The prevalence of obesity, diabetes, hypertension, and hyperlipidemia will be calculated as proportions with corresponding 95% confidence intervals (CIs). Each condition will be defined according to standard clinical criteria.

Bivariate analyses will be conducted to assess associations between each outcome variable (obesity, diabetes, hypertension, and hyperlipidemia) and independent variables such as age, sex, socioeconomic status, physical activity, dietary habits, smoking status, and family history. The Chi-square test (or Fisher's exact test where appropriate) will be used for associations between categorical variables. Independent sample t-tests or Mann-Whitney U tests will be applied for comparisons involving continuous variables, depending on data distribution.

Multivariable logistic regression analysis will be performed to identify independent factors associated with each outcome. Separate regression models will be constructed for obesity, diabetes, hypertension, and hyperlipidemia. Variables with a p-value <0.20 in bivariate analysis, as well as those considered clinically relevant, will be included in the multivariable models. Adjusted odds ratios (AORs) with 95% confidence intervals will be reported. Model assumptions will be assessed, including multicollinearity using variance inflation factors (VIF).

Missing data will be assessed for extent and pattern. If the proportion of missing data is minimal (<5%), complete case analysis will be performed. For higher levels of missingness, appropriate methods such as multiple imputation may be considered.

All statistical tests will be two-sided, and a p-value of <0.05 will be considered statistically significant.

Follow-up Analysis (3-Month Cohort of at-Risk Individuals) Participants identified as at-risk at baseline will be enrolled in a 3-month follow-up cohort. Laboratory investigations and clinical measurements will be obtained at baseline and at 3 months.

Changes in clinical and laboratory parameters (e.g., blood glucose, blood pressure, lipid profile, BMI) between baseline and 3 months will be assessed using paired t-test for normally distributed variables and Wilcoxon signed-rank test for non-normally distributed variables. Effect of treatment and adherence outcomes will be compared across treatment groups (on treatment vs not on treatment) and adherence categories (good vs poor adherence) using independent t-test or Mann-Whitney U test for two groups and ANOVA or Kruskal-Wallis test for more than two groups as appropriate.

Regression models (e.g., linear regression for continuous outcomes, logistic regression for binary outcomes) will be used to assess predictors of improvement at 3 months, adjusting for baseline values and potential confounders.
