Conditions

Physical and mental health of postpartum women Pregnancy and Childbirth

Interventions

Based on the noise levels recorded in their respective wards, with a cut-off value of 40 dB, patients were divided into two groups: the conventional group and the noise reduction group (NR group): 1.

Design outcomes

Primary

Measure	Time frame
1. Postpartum anxiety: state and trait anxiety levels assessed using the State-Trait Anxiety Inventory (STAI) at baseline (before treatment), postpartum day 1, day 3, and day 4 (one day before discharge) 2. Sleep quality evaluated using the Pittsburgh Sleep Quality Index (PSQI) at baseline (before treatment) and 4 days postpartum 3. Physiological indicators: CRP levels, prolactin levels, systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP), pulse rate, respiratory rate, and body temperature measured using bedside monitors (GE Healthcare, USA) and tympanic thermometers (Exergen, USA) at baseline, postpartum day 1, day 3, and day 4	—

Secondary

Measure	Time frame
1. Socio-demographic data: age, education level, marital status, occupation, medical history, previous intensive care experiences, and reasons for current hospitalization are measured using routine hospital documentation at baseline. 2. Noise levels are measured using a sound-level meter (SLM) (NL-22 Type II, RION, Japan) continuously every second over a 3-month period, with data averaged at four key timepoints per day (8:00, 14:00, 20:00, and 2:00).	—
