Abstract

Background: Osteoporosis is a major global health issue that results in disability and high medical expenses. It can significantly impact both individuals and their caregivers, leading to pain, limitations in daily activities, and emotional distress. Purpose: This study observed the association of sociodemographic factors in affecting knowledge, perception, and behavior related to osteoporosis in a rural area of Malang, Indonesia. Methods: A cross-sectional study was conducted in a rural area of Malang to assess the knowledge, perception, and behavior of adults (≥18 years old) toward osteoporosis. Participants were asked to fill in a validated questionnaire, which was selected randomly using a multistage stratified sampling technique. Collected data were analyzed on SPSS for Windows version 25.0. Results: The study included 376 randomly selected participants from various rural areas in Malang. The subjects mostly were within the 51-60 age group (34.0%), with female respondents accounting for 73.4% of the sample. On average, participants scored 1.8 (±2.5) for knowledge, 12.0 (±2.1) for perception, and 12.2 (±2.9) for behavior regarding osteoporosis. Both age and education levels showed associations with knowledge and perception, while only age was significantly linked to behavior concerning osteoporosis. Conclusions: Our study revealed a strong association between low educational levels, especially among the elderly, and the lack of knowledge, perceptions, and behavior toward osteoporosis.

Abstract

Knee alignment affects lower limb biomechanics and functional knee movement. However, the relationship between knee alignment and knee flexion range of motion (ROM) in healthy populations, particularly across different age groups, remains unclear. To compare coronal and sagittal knee alignment and knee flexion ROM between healthy young adults and elderly individuals, and to examine the association between knee alignment and knee flexion ROM using clinical goniometric assessment. This cross-sectional study included 64 healthy participants (32 young adults aged 20–24 years and 32 elderly individuals aged ≥60 years). Coronal and sagittal knee alignment and active knee flexion ROM were measured using a goniometer. Group differences were analyzed using independent t-tests and Chi-square tests, and associations between alignment categories and knee flexion ROM were assessed using the Kruskal-Wallis test. Elderly participants showed a higher prevalence of coronal varus alignment and sagittal flexion contracture compared with young adults. Mean knee flexion range of motion was significantly lower in elderly participants than in young adults (127.4±4.7° vs 137.6±4.4°, p<0.001). Coronal knee alignment was not significantly associated with knee flexion ROM in either young adults (p=0.056) or elderly participants (p=0.476). In contrast, sagittal knee alignment demonstrated a significant association with knee flexion ROM in elderly participants (p=0.017), whereas no significant association was observed in the young adult group (p=0.922). Sagittal knee alignment, rather than coronal alignment, correlates with reduced knee flexion range of motion in healthy elderly individuals. A straightforward clinical evaluation of sagittal alignment may assist in detecting early functional deterioration in ageing populations.
