Health Beyond Disease: An Integrated Assessment of Quality of Life, Perceived Health, and Lifestyle Behaviours in a Peri-Urban Kenyan Population—A Pilot Study

Background/Objective: Health is a multidimensional construct shaped not only by clinical conditions but also by psychological, social, environmental and cultural factors. In low- and middle-income countries undergoing rapid epidemiological transition, understanding health requires integrated and culturally informed approaches. However, quality of life, perceived health status and lifestyle behaviors are often investigated separately, limiting the interpretation of well-being in specific local contexts. This study aimed to provide an integrated assessment of quality of life, perceived health status and lifestyle behaviours among adults attending a peri-urban public hospital in Kenya, using internationally validated instruments applied within a specific local cultural context. Methods: A cross-sectional observational study was conducted at Tigoni Level 4 Hospital, Kiambu County, Kenya. Adult outpatients (N = 40) were consecutively recruited. Quality of life was assessed using the WHOQOL-BREF, perceived health status using the EQ-5D-5L and EQ-VAS, and lifestyle behaviours using selected modules of the WHO STEPS instrument. Descriptive statistics were performed, and exploratory associations were examined using Spearman’s rank correlation coefficient. Results: Participants had a mean age of 35.9 ± 11.4 years, with a balanced gender distribution. Lifestyle risk factors were prevalent, including insufficient physical activity (40%) and overweight or obesity (>50%). WHOQOL-BREF scores revealed a heterogeneous profile, with relatively preserved social relationships and lower scores in the psychological and environmental domains. Pain/discomfort and anxiety/depression were the most frequently reported EQ-5D-5L problems. The mean EQ-VAS score was 68.2 ± 15.7. Perceived health was positively associated with physical and psychological quality of life, while higher body mass index was associated with lower physical quality of life. Mental health emerged as a cross-cutting factor across instruments. Conclusions: The findings highlight the multidimensional nature of health in a peri-urban Kenyan context and suggest the importance of considering local social and cultural influences when interpreting standardized health measures. Mental health and environmental conditions play a central role in shaping quality of life and perceived health, while lifestyle risk factors are already prevalent in a relatively young outpatient population. Integrating standardized health measures within a cross-cultural framework may support more holistic and person-centred approaches in primary care and public health in similar settings.
