Proposal for a composite index of alcohol problems

Area of Science:

• Public Health
• Health Economics
• Statistics

Background:

• Measuring the severity of alcohol problems is complex due to varying indicators.
• Existing statistical series (consumption, morbidity, mortality, traffic offenses) show divergent provincial rankings.
• Composite indicators, similar to economic indexes, can offer a more unified measure.

Purpose of the Study:

• To construct a composite index for measuring the severity of alcohol problems in Canadian provinces.
• To address inconsistencies in provincial rankings derived from individual statistical series.
• To provide a more reliable and consistent measure of alcohol-related issues across regions.

Main Methods:

• Utilized the index number method to construct composite indexes.
• Incorporated statistical series for alcohol consumption, morbidity, mortality, and alcohol-related traffic offenses.
• Analyzed data from 1975, 1980, 1985, and 1990 across ten Canadian provinces.
• Employed Spearman, Pearson correlations, and Kendall's coefficient of concordance for statistical analysis.

Main Results:

• Individual statistical series yielded different provincial rankings for alcohol problem severity.
• The composite index demonstrated relatively consistent provincial rankings across different time periods.
• Identified provinces with consistently high (PEI, AB, BC, SK), mid-range (MB, NS, ON), and low (NB, NL, QC) composite indexes.

Conclusions:

• A composite index effectively resolves discrepancies found in individual statistical series.
• The developed composite index offers a stable and reliable method for assessing and comparing provincial alcohol problem severity.
• Findings highlight regional variations in alcohol-related issues across Canada, with implications for targeted public health interventions.
