Field study on pregnant women’s thermal preference in different trimesters in winter

Description

The data were used to analyze the differences in the thermal preference of pregnant women in different trimesters and their impact factors. This dataset includes data of questionnaire information, graphs, and tables. The questionnaire information included the subject's age, height, pre-pregnancy weight, current weight, pregnancy week, pregnancy diseases, and thermal preference questionnaire. Pregnancy diseases include hyperthyroidism, hypothyroidism, anemia, diabetes, hypertension, and hypotension et al. The thermal preferences questionnaire was designed according to the psychological and behavioral aspects of pregnant women, and the options corresponding to cool, neutral, and warm preferences were designed. A total of 1388 questionnaires were collected, including participants in the first trimester (225), second trimester (498), and third trimester (665). In addition, a total of four thermal environmental parameters, i.e., air temperature (Ta), air velocity (Va), black globe temperature (Tg), and relative humidity (RH), were tested in the obstetric waiting room in the hospital. They were recorded by an environmental multiparameter detector (model Testo 400). The findings showed that the thermal preference of pregnant women shifted from warm preference to cool preference as pregnancy developed. The differences in thermal preference of pregnant women were associated with pregnancy diseases, pre-pregnancy body mass index (PBMI), and exercise.
