Open Access research with a real impact on health...

The Strathprints institutional repository is a digital archive of University of Strathclyde's Open Access research outputs. Strathprints provides access to thousands of Open Access research papers by Strathclyde researchers, including by researchers from the Physical Activity for Health Group based within the School of Psychological Sciences & Health. Research here seeks to better understand how and why physical activity improves health, gain a better understanding of the amount, intensity, and type of physical activity needed for health benefits, and evaluate the effect of interventions to promote physical activity.

The increasing number of cases of serogroup C meningococcal disease in Scotland in the late 1990s coincided with the availability of a new meningococcal conjugate serogroup C (MCC) vaccine that, from 1999 onwards, was offered to all individuals aged <20 years. Annual incidence rates between 1994 and 2003 were calculated in 3 age groups (<5 years old; 5-19 years old; and 20 years old), and Poisson regression models were used to verify disease trends over time. Dramatic reductions ( ) in the incidence of serogroup C meningococcal disease were seen in target age groups: from 15.8 incidents per 100,000 subjects in 1999 (95% confidence interval [CI], 11.3-20.3) to 0.7 incidents per 100,000 subjects in 2001 (95% CI, −0.3 to 1.6), for subjects <5 years old, and from 6.7 incidents per 100,000 subjects in 1999 (95% CI, 5.1-8.3) to 1.5 incidents per 100,000 subjects in 2001 (95% CI, 0.7-2.3), for subjects 5-19 years old. An increasing incidence of serogroup B meningococcal disease in individuals 5-19 years old was clearly established before the campaign began. A 30% decrease in the case‐fatality rate for individuals <20 years old was not significant ( ). The MCC vaccine program has been highly effective in Scotland, leading to substantial reductions in serogroup C meningococcal disease and meningococcal mortality, with no adverse effects on other groups.
