Journal Article
Reidpath, D. D., Davey, T. M., Kadirvelu, A., Soyiri, I. N., & Allotey, P. (2014). Does one cigarette make an adolescent smoker, and is it influenced by age and age of smoking initiation? Evidence of association from the U.S. Youth Risk Behavior Surveillance System (2011). Preventive Medicine, 59(1), 37-41. https://doi.org/10.1016/j.ypmed.2013.11.011

Objectives: Evidence that age of smoking initiation represents a risk factor for regular smoking in adolescence is complicated by inconsistencies in the operational definition of smoking initiation and simultaneous inclusion of age as an explanatory... Read More

Forecasting higher than expected numbers of health events provides potentially valuable insights in its own right, and may contribute to health services management and syndromic surveillance. This study investigates the use of quantile regression to... Read More

Validity of self-measured waist and hip circumferences: results from a community study in Malaysia (2013)
Journal Article
Reidpath, D. D., Cheah, J. C. H., Lam, F., Yasin, S., Soyiri, I., & Allotey, P. (2013). Validity of self-measured waist and hip circumferences: results from a community study in Malaysia. Nutrition Journal, 12(1), https://doi.org/10.1186/1475-2891-12-135

Background: Measures of central adiposity are better predictors of adverse health events than BMI. Nonetheless, BMI is more widely used in health research. One reason for this may be the limited research supporting the self-measurement of waist and h... Read More

Predictors of fetal anemia and cord blood malaria parasitemia among newborns of HIV-positive mothers (2013)
Journal Article
Laar, A. K., Grant, F. E., Addo, Y., Soyiri, I., Nkansah, B., Abugri, J., …Quakyi, I. A. (2013). Predictors of fetal anemia and cord blood malaria parasitemia among newborns of HIV-positive mothers. BMC research notes, 6(1), https://doi.org/10.1186/1756-0500-6-350

Background: Malaria and HIV infections during pregnancy can individually or jointly unleash or confound pregnancy outcomes. Two of the probable outcomes are fetal anemia and cord blood malaria parasitemia. We determined clinical and demographic facto... Read More
