During pregnancy, structural and functional changes usually occur in the body, which has various consequences, including lower back pain (LBP) and hypothyroidism. One of the risk factors for these problems is physical inactivity.
This study aimed to investigate the association of back pain and physical inactivity, weight gain, and hypothyroidism in pregnant women.
In this cohort study, 420 pregnant women (26.333 ± 5.820 years old) were included. At first, participants answered this question: "Do you have any plans for pregnancy in the next month?" If the answer was yes, further evaluations were performed. The physical activity and pain intensity were measured by the International Physical Activity Questionnaire Short Form (IPAQ-S) and Visual Analogue Scale. Serum TSH was measured by automated chemiluminescence and commercial kits. Measurements were conducted before, the first, second, and third trimester of pregnancy.
Women reporting LBP were less engaged in physical activities and weight gained in the second and third trimesters of pregnancy was significantly higher than pregnant women without LBP (p< 0.05). TSH level and weight gained in pregnant women with low physical activity level was significantly higher than pregnant women with moderate and high physical activity (p< 0.05) (without significant difference in TSH and BMI). The physical inactivity (before: OR: 1.11 95% CI: 0.89 to 1.22; first trimester: OR: 1.09 95% CI: 1.02 to 1.59; second trimester: OR: 0.92 95% CI: 0.87 to 1.31; third trimester: OR: 1.12 95% CI: 1.02 to 1.39), TSH (OR: 0.85 95% CI: 0.57 to 1.29), and weight gain (second trimester: OR: 0.87 95% CI: 0.92 to 1.59; third trimester: OR: 1.44 95% CI: 1.02 to 1.98; p< 0.05) did predict increased pain intensity.
Using health-oriented approaches to increase physical activity and normalize thyroid function and weight gain during pregnancy can have beneficial effects on LBP.
怀孕期间，身体通常会发生结构和功能变化，这会带来各种后果，包括下背痛（LBP）和甲状腺功能减退症。这些问题的一个风险因素是身体活动不足。
本研究旨在探讨孕妇背痛与身体活动不足、体重增加和甲状腺功能减退症之间的关系。
在这项队列研究中，纳入了 420 名孕妇（26.333±5.820 岁）。首先，参与者回答了这个问题：“你是否计划在接下来的一个月怀孕？”如果答案是肯定的，则进行进一步评估。身体活动和疼痛强度通过国际体力活动问卷短表（IPAQ-S）和视觉模拟量表进行测量。血清 TSH 通过自动化化学发光和商业试剂盒进行测量。测量在怀孕前、第一、二和三个月进行。
报告有 LBP 的女性身体活动量较少，且在怀孕第二和第三个月体重增加明显高于无 LBP 的孕妇（p<0.05）。低体力活动水平的孕妇 TSH 水平和体重增加明显高于中、高体力活动水平的孕妇（p<0.05）（TSH 和 BMI 无显著差异）。体力活动不足（怀孕前：OR：1.11，95%CI：0.89 至 1.22；第一孕期：OR：1.09，95%CI：1.02 至 1.59；第二孕期：OR：0.92，95%CI：0.87 至 1.31；第三孕期：OR：1.12，95%CI：1.02 至 1.39）、TSH（OR：0.85，95%CI：0.57 至 1.29）和体重增加（第二孕期：OR：0.87，95%CI：0.92 至 1.59；第三孕期：OR：1.44，95%CI：1.02 至 1.98；p<0.05）预测疼痛强度增加。
采用以健康为导向的方法增加身体活动、使甲状腺功能和体重增加正常化，可能对 LBP 有益。
