The evaluation of the harmonization potential was performed using the study questionnaires and data dictionaries from baseline assessments. The harmonization potential evaluation consisted of 126 variables and included 13 cohort studies, encompassing 15 datasets, totalling almost 2 million participants.

The CHPT generic harmonized dataset covers:

  • Participant’s individual history of diseases: cancer, endocrine and metabolic diseases (diabetes), circulatory system diseases (high blood pressure, myocardial infarction, stroke), respiratory system diseases (asthma, chronic obstructive pulmonary disease, chronic bronchitis, emphysema)
  • Participant’s socio-demographic factors: age, sex, education, working status, marital status, income, family/household structure
  • Participant’s physical measures: anthropometric measures, heart rate, systolic and diastolic blood pressure
  • Participant’s reproductive health factors: occurrence and onset of menstruation, menopause, hysterectomy, and oophorectomy, gravidity, live births, contraceptive use and hormone replacement therapy use
  • Participant’s behavioral and lifestyle factors: cigarette smoking, passive smoking exposure, alcohol consumption, physical activity, nutrition.

- study-specific variable is the same as DataSchema variable (status = identical) or needs transformation to generate DataSchema variable (status = compatible)
- study does not collect DataSchema variable (status = unavailable) or cannot be used to generate DataSchema variable (status = incompatible)
- harmonization status not determined
Not Applicable
- Harmonization status is not relevant
