Objectives |
This study aimed to estimate total and age-specific incidence rates of HZ with data from electronic clinical records in primary care (ECRPC) and to analyze trends by sex and age.
Methods |
Descriptive cross-sectional study covering the incident HZ episodes registered in the ECRPC of the Madrid Regional Public Health System in 2005–2012. Annual crude and age-adjusted incidence rates were calculated. Differences by sex and age were assessed by poisson regression. The annual percentage of change (APC) of incidence rates and ‘breakthrough points’ of the time trends were determined with the Joinpoint Regression Program.
Results |
211,650 episodes of HZ were identified (60.6% women, 52.2% > 55 years). The incidence rate increased from 363.21 to 481.92 per 100,000 person-year in 2005–2012. Rates were higher among women and increased with age. The APC for the period was 3.59% in men and 3.67% in women (p < 0.05). Age-specific rates increased in patients over 14 years. The APC in the 25–44 age group was 7.4% since 2007. The incidence rate ratio (women/men) was highest in this group.
Conclusions |
The incidence of HZ presents an upward trend in 2005–2012 in adults and the elderly. Monitoring the incidence and age-specific rates, will help to detect changes in trends.
