Prevalensi populasi kecemasan di Indonesia, berdasarkan Riset Kesehatan Dasar tahun 2013 menunjukkan terdapat 14 juta orang yang mengalami Kecemasan dan 6% terjadi pada usia remaja >15 tahun. Studi menunjukkan kecemasan dapat berisiko tinggi menyebabkan nyeri punggung bawah. Walaupun telah dilaporkan bahwa terdapat hubungan kecemasan menggunakan kuesioner Depression, Anxiety, & Stress Scale (DASS) dengan nyeri punggung bawah, namun belum pernah diteliti mengenai hubungan tingkat kecemasan ringan, sedang, & berat menggunakan kuesioner Hamilton Anxiety Rating Scale (HARS) yang lebih spesifik, terhadap kejadian nyeri punggung bawah. Metode yang digunakan secara cross-sectional dengan jumlah sampel minimum 112 orang. Pengambilan sampel dilakukan dengan teknik acak sederhana dengan meliputi kriteria inklusi dan eksklusi pada setiap partisipan. Partisipan akan diberikan lembar informed consent, data demografis, Hamilton Anxiety Rating Scale, dan Roland Morris Disability Questionnaire melalui google form yang disebarkan kepada mahasiswa FK UPH angkatan 2019-2021. Data yang didapat akan dianalisis menggunakan aplikasi SPSS dengan metode Chi-square. Hasil uji analisis bivariat Chi-square menunjukkan adanya hubungan signifikan setiap tingkat kecemasan ringan, sedang, & berat terhadap nyeri punggung bawah (p-value = <=0.05). Masing-masing tingkat kecemasan ringan, sedang, & berat memiliki peluang 2.833, 15.136, & 11.212 kali lebih besar mengalami nyeri punggung bawah./ The prevalence of anxiety population in Indonesia, based on the 2013 Basic Health Research, shows that there are 14 million people who experience anxiety and 6% of them are teenagers > 15 years old. Studies show anxiety can increase the risk of low back pain. Although it is reported that there is a relationship between anxiety using the Depression, Anxiety, & Stress Scale (DASS) questionnaire with low back pain, there has never been a study on the relationship between anxiety levels of severity: mild, moderate, & severe using the Hamilton Anxiety Rating Scale (HARS) questionnaire which is more specific, to the incidence of low back pain. The method used is cross-sectional with a minimum sample size of 112 people. Sampling was carried out in a simple random technique with inclusion and exclusion criteria for each participant. Participants will be given informed consent sheet, demographic data sheet, Hamilton Anxiety Rating Scale Questionnaire, and Roland Morris Disability Questionnaire through a google form distributed to students of UPH Medical Faculty batch 2019-2021. The data obtained will be analyzed using the SPSS application with the Chi-square method. The results of the Chi-square bivariate analysis test showed that there was a significant relationship between mild, moderate and severe levels of anxiety on low back pain (p-value = <=0.05). Each level of mild, moderate, & severe anxiety has a 2.833, 15.136, & 11.212 times greater chance of experiencing low back pain.
