To explore the relationship between the hypertensive snowbirds' length of migratory stay and their blood pressure control and blood pressure levels. This study was a cross-sectional study. A population of snowbirds with hypertension was recruited between October and November 2022, and a structured questionnaire was used to collect their self-measured blood pressure and length of stay in Hainan Province. The blood pressure control status is determined based on self-measured blood pressure. According to the self-measured blood pressure to determine whether the blood pressure was well controlled. The associations between snowbirds' length of stay and their blood pressure control as well as their self-measured blood pressure were analyzed using restricted cubic splines. A total of 362 research subjects were included, 169(46.7%) of whom were male, and their age was (69.7±7.0) years old. The participants' self-measured systolic blood pressure and diastolic blood pressure were (129.1±16.2) mmHg (1 mmHg=0.133 kPa) and (78.9±10.1) mmHg, respectively. Overall, 174 (48.1%) participants attained adequate blood pressure control. The median length of stay in Wuzhishan City was 7(6, 7) months. There was an inverted U-shaped association between snowbirds' length of stay and blood pressure control (overall: 0.023; nonlinearity: =0.014), where participants with a length of stay of 7 months had the highest rate of blood pressure control. There is a U-shaped curve relationship between length of stay and systolic blood pressure (overall: 0.001; nonlinearity: =0.033), and a linear negative correlation with diastolic blood pressure (=-1.19, =0.003). Compared with hypertensive snowbirds with too long or too short lengths of stay, snowbirds who stayed in Wuzhishan City for seven months have better blood pressure control, and systolic blood pressure is also lower.
探讨高血压候鸟人群的迁徙停留时长与其血压控制情况及血压水平之间的关系。本研究为横断面研究。于2022年10月至11月招募了一群患有高血压的候鸟人群，并使用结构化问卷收集他们的自测血压及在海南省的停留时长。根据自测血压确定血压控制状况。依据自测血压判断血压是否得到良好控制。采用受限立方样条分析候鸟人群的停留时长与其血压控制情况以及自测血压之间的关联。共纳入362名研究对象，其中男性169名（46.7%），年龄为（69.7±7.0）岁。参与者的自测收缩压和舒张压分别为（129.1±16.2）mmHg（1 mmHg = 0.133 kPa）和（78.9±10.1）mmHg。总体而言，174名（48.1%）参与者实现了血压的充分控制。在五指山市的停留时长中位数为7（6，7）个月。候鸟人群的停留时长与血压控制之间存在倒U形关联（总体：0.023；非线性：=0.014），停留时长为7个月的参与者血压控制率最高。停留时长与收缩压之间存在U形曲线关系（总体：0.001；非线性：=0.033），与舒张压呈线性负相关（=-1.19，=0.003）。与停留时长过长或过短的高血压候鸟人群相比，在五指山市停留7个月的候鸟人群血压控制更好，收缩压也更低。
