Design outcomes
Primary
| Measure | Time frame |
|---|---|
| There is no singular outcome as WP1 will measure a host of personal and environmental exposures from personal monitoring, sensors, biosamples, and questionnaires. Similarly, there will be sensor data, questionnaires, and interviews for WP7 which will be used to describe environmental exposure. Measures occurring at the clinical examination visit: 1. Anthropometry for height and weight is measured using SECA scales and the Leister Height Measure d=1mm; waist circumference is measured using a flexible tape measure. These are measured at one point in time and can be conducted up to 7 days before baseline (the start of the monitoring period) or 7 days after blood collection. 2. Bioimpedance is measured using the Bodystat 1500NDD device at one point in time and can be conducted up to 7 days before baseline (the start of the monitoring period) or 7 days after blood collection. 3. Blood pressure is measured using the OMRON electronic 705-CP11 device at one point in time and can be conducted up to 7 days before baseline (the start of the monitoring period) or 7 days after blood collection. 4. Spirometry is measured using the EasyOne spirometry device at one point in time and can be conducted up to 7 days before baseline (the start of the monitoring period) or 7 days after blood collection. 5. Neurodevelopment is measured using the N-back test (working memory), Roulettes task (risk-taking preferences), and Raven Standard Progressive Matrices (non-verbal general intelligence). These are computerized tasks that are conducted at one point in time and can be conducted up to 7 days before baseline (the start of the monitoring period) or 7 days after blood collection. Biological samples: 1. Environmental exposures measured from hair (50 mg or ~1 cm² of scalp area) collected close to the scalp using scissors at one point in time and can be conducted at any time relative to the baseline visit. 2. Phthalates measured from urine samples (collected using the Vitrex Vacusense 112510 k | — |
