Adjusted associations between measures of secondary pesticide exposure and blood pressure and heart rate differences among children (n = 271).
| Predictor | Model 1 SBP [mmHg (95% CI)] | Model 1 DBP [mmHg (95% CI)] | Model 1 heart rate [BPM (95% CI)] | Model 2 SBP [mmHg (95% CI)] | Model 2 DBP [mmHg (95% CI)] | Model 2 heart rate [BPM (95% CI)] |

| BPM, beats per minute. Model 1: age, sex, race, height-for-age z-score and examination date. When the predictor was AChE activity, hemoglobin concentration was also included in the model. Model 2: model 1 + heart rate, income, number of smokers living at home, residence distance to nearest flower plantation edge, pesticide use within household lot, and pesticide use by contiguous neighbors. When heart rate was the outcome of interest, model 2 did not include heart rate as an adjustment variable; when the predictor was AChE activity, flower worker cohabitation was added to the model. an = 228. *p < 0.05. **p = 0.06. #p = 0.052. | ||||||
