Abstract

Background: Insomnia is an important public health concern and may be particularly relevant among security personnel because of irregular work schedules, occupational demands, sustained vigilance, and inadequate rest. This study was conducted to determine the prevalence of insomnia and its association with selected sociodemographic and health-related factors among security personnel in a tertiary care government hospital in south India.

Methods: A cross-sectional study was conducted among 100 security personnel. Sociodemographic characteristics, including age, gender, income, education, and marital status, and health-related characteristics, including body mass index, diabetes, and hypertension, were assessed using a structured questionnaire. Insomnia was assessed using the Insomnia Severity Index (ISI). Associations between insomnia and selected variables were examined using the chi-square test.

Results: Sub-threshold insomnia was present in 32% of participants, while no cases of moderate or severe insomnia were identified. Significant associations were observed between insomnia and gender (p=0.019) and income level (p=0.020). No significant associations were observed with age, education, marital status, or metabolic health status. Self-reported Diabetes and Hypertension were present in 10% and 4% of participants, respectively, while 74% were classified as obese.

Conclusions: Although moderate or severe insomnia was not observed, nearly one-third of security personnel had sub-threshold insomnia. Workplace-based sleep hygiene interventions may be beneficial, particularly among women and lower-income employees. Further studies incorporating objective sleep assessments and detailed evaluation of shift schedules are warranted.
