Study Population: \(N =
173\)
Statistical Tool: R Version 4.x
Objective: This study aimed to determine the
prevalence of substance abuse and identify significant demographic,
socioeconomic, and environmental predictors among a sample of 173
respondents.
Method: A cross-sectional quantitative design was
utilized. Data analysis included frequency distributions, Pearson’s
Chi-square tests for bivariate associations, and binary logistic
regression for multivariate prediction.
Results: The prevalence of substance abuse was 46.2%
(\(n = 80\)). Bivariate analysis showed
that marital status was significantly associated with substance abuse,
\(\chi^2(3) = 10.74, p = .013\). In the
multivariate model, Marital Status Category 2 was a significant
protective factor (\(OR = 0.27, p <
.001\)), while Environmental factors (Category 2) showed a
borderline significant risk (\(OR = 3.99, p =
.052\)).
Conclusion: Substance abuse affects nearly half of the
population studied. Marital status and environmental conditions are the
primary drivers, suggesting that social support and environmental
modifications are key to intervention.
Substance abuse remains a critical public health challenge, impacting individual well-being and community stability. Understanding the specific demographic and environmental drivers is essential for creating targeted prevention programs. This report analyzes data from 173 participants to pinpoint which factors—ranging from age to living environment—most significantly influence substance use patterns.
The study employed a cross-sectional survey design with 173 respondents. The sample was analyzed to determine the relationship between a binary outcome (Substance Abuse: Yes/No) and several independent variables.
Descriptive statistics established prevalence. Pearson’s Chi-square tests were used to filter variables for bivariate significance. Finally, a binary logistic regression model was used to calculate Odds Ratios (\(OR\)) and 95% Confidence Intervals (\(CI\)), identifying the independent weight of each predictor while controlling for others.
The first stage of analysis determined the extent of substance abuse within the sample.
Table 1: Prevalence of Substance Abuse Among Respondents (\(N=173\))
| Category | Frequency (\(n\)) | Percentage (%) |
|---|---|---|
| Substance Abuse (Yes) | 80 | 46.24% |
| No Substance Abuse | 93 | 53.76% |
| Total | 173 | 100.00% |
Interpretation: The data reveals a high prevalence rate, with 46.24% of respondents reporting substance abuse. This indicates that the issue is widespread within the surveyed group, affecting nearly one out of every two individuals.

Table 2: Chi-Square Test of Independence for Factors Associated with Substance Abuse
| Variable | \(\chi^2\) | \(df\) | \(p\)-value |
|---|---|---|---|
| Age | 1.77 | 2 | .413 |
| Marital Status | 10.74 | 3 | .013* |
| Residence Area | 0.94 | 3 | .815 |
| Socioeconomic (Coded) | 2.41 | 2 | .299 |
| Environmental (Coded) | 2.33 | 1 | .127 |
| Household (Coded) | 0.00 | 1 | 1.000 |
Note. Significance level set at \(p < .05\).
Interpretation: Marital Status was the only variable to show a statistically significant association with substance abuse at the bivariate level (\(p = .013\)). Other factors, such as Age and Residence, did not show a direct significant relationship when tested independently.
A binary logistic regression was conducted to identify the independent predictors of substance abuse while controlling for all variables simultaneously.

| Predictor | \(OR\) | \(95\% CI\) | \(p\)-value |
|---|---|---|---|
| (Intercept) | 0.65 | [0.13, 2.79] | .580 |
| Age (Category 2) | 0.53 | [0.25, 1.10] | .090 |
| Age (Category 3) | 0.73 | [0.30, 1.79] | .494 |
| Marital Status (Cat 2) | 0.27 | [0.12, 0.55] | <.001* |
| Marital Status (Cat 3) | 0.83 | [0.24, 2.98] | .775 |
| Marital Status (Cat 4) | 0.96 | [0.20, 4.46] | .962 |
| Residence (Area 2) | 1.64 | [0.75, 3.67] | .218 |
| Residence (Area 3) | 0.75 | [0.32, 1.73] | .501 |
| Socioeconomic (Cat 3) | 3.74 | [0.90, 17.73] | .078 |
| Environmental (Cat 2) | 3.99 | [1.06, 18.18] | .052 |
Note. \(OR\) = Odds Ratio; \(CI\) = Confidence Interval. Significance level \(p < .05\).
Interpretation of Regression Results: 1. Marital Status (Cat 2): This is a highly significant protective factor. Respondents in this category are 73% less likely (\(OR = 0.27\)) to report substance abuse compared to the reference group. 2. Environmental Factors (Cat 2): This factor showed a borderline significant risk (\(p = .052\)). The Odds Ratio of 3.99 suggests that individuals in this environmental category are nearly 4 times more likely to engage in substance abuse than those in the reference category. 3. Socioeconomic Factors: While not reaching the .05 significance threshold (\(p = .078\)), the \(OR\) of 3.74 indicates a strong trend toward increased risk for Category 3.
The findings highlight that substance abuse is not randomly distributed but is tied to specific social and environmental structures.
Substance abuse prevalence is alarmingly high at 46.2%. The study concludes that marital status is the most powerful demographic predictor of substance abuse, while environmental conditions represent a major risk factor.
