The objective of this study was to estimate the prevalence of different bedroom habits/preferences, and to assess whether these habits/preferences differ with age and sex.
A population-based Norwegian cross-sectional telephone survey with 1001 of 1599 randomly selected adults (63% response rate) was performed. The questions about habits and preferences had different response alternatives (yes/no; up to eight response alternatives). Mean age was 47.5 years, and split into four groups (18-29, 30-44, 45-59, 60+ years). Age and sex differences were explored with chi-square statistics.
Electronic media use in bed after bedtime was more common in younger compared to older age groups, with no sex difference. Daily use was reported by 61.8% of participants aged 18-29 years, compared to 3.7% among participants of 60+ years. Reading in bed after bedtime was more common with increasing age, and more common among females compared to males. Females and older participants more often rated their bed as very good. The older the participants, the colder the reported bedroom temperature. During winter, 48.5% of participants aged 60+ years reported a bedroom temperature of ≤12 °C. Many participants (39.2%) reported having their bedroom window always open at night, with no sex difference, but an increase with increasing age. Blackout curtains were used by 63.3%, with a drop in use with increasing age. Most participants preferred lying on the side when trying to sleep. Fewer older compared to younger participants preferred lying on the stomach.
The findings may stimulate further studies exploring whether these habits/preferences may influence sleep and sleep disorders.
本研究旨在评估不同卧室习惯/偏好的流行程度，并评估这些习惯/偏好是否因年龄和性别而异。
进行了一项基于人群的挪威横断面电话调查，共纳入 1599 名随机选择的成年人中的 1001 名（63%的应答率）。关于习惯和偏好的问题有不同的应答选择（是/否；最多 8 个应答选择）。平均年龄为 47.5 岁，分为四个年龄组（18-29 岁、30-44 岁、45-59 岁、60+岁）。采用卡方检验探索年龄和性别差异。
与年龄较大的组相比，年轻人在就寝后在床上使用电子媒体更为常见，且无性别差异。18-29 岁的参与者中，61.8%报告每天使用电子媒体，而 60+岁的参与者中，这一比例为 3.7%。就寝后在床上阅读的比例随着年龄的增长而增加，且女性比男性更为常见。女性和年龄较大的参与者更常认为自己的床非常好。参与者年龄越大，报告的卧室温度越低。在冬季，60+岁的参与者中有 48.5%报告卧室温度≤12°C。许多参与者（39.2%）报告说他们的卧室窗户整晚都开着，无性别差异，但随着年龄的增长而增加。遮光窗帘的使用率为 63.3%，随着年龄的增长而下降。大多数参与者在尝试入睡时更喜欢侧卧。与年轻人相比，年龄较大的参与者更喜欢仰卧。
这些发现可能会激发进一步的研究，探讨这些习惯/偏好是否会影响睡眠和睡眠障碍。
