Abstract

Central obesity can increase mechanical stress and inflammation on the spine, which can lead to low back pain (LBP). Housewives have limited physical activity and repetitive domestic workloads that can exacerbate this risk. Objective to determine the relationship between central obesity and low back pain complaints among housewives in Kampung Sawah Village, West Sumba. Method: A cross-sectional analytical study of 101 housewives. Methods: The study used an observational analytical design with a cross-sectional approach. A total of 101 housewives were included as respondents. Central obesity was determined based on waist circumference measurements, while LBP complaints were assessed using a standardised questionnaire. The analysis of the relationship between variables was performed using the Chi-Square test. Results of the total respondents, 89 people (88.1%) were identified as having central obesity, and 67 of them reported complaints of LBP. The Chi-Square test showed a value of p=0.001, indicating a significant relationship between central obesity and complaints of low back pain. There is a significant relationship between central obesity and LBP complaints among housewives in Kampung Sawah Village, West Sumba. Prevention can be achieved through increased physical activity and education on ergonomic work posture.

Abstract

Hypertension is a significant worldwide health concern that greatly affects heart-related illnesses and deaths. One recommended method to help lower blood pressure without medication is the isometric handgrip exercise. This research aimed to investigate the impact of isometric handgrip exercise on lowering blood pressure in those with prehypertension and stage 1 hypertension. The study utilized a quasi-experimental design following a two-group pretest–posttest format. The participants included 50 seminarians from Seminari Tinggi St. Mikhael Penfui, Kupang, who were chosen through purposive sampling based on specific inclusion and exclusion criteria. The participants were split into two groups: the intervention group (n = 25) that engaged in isometric handgrip exercises for three minutes daily over five days, and the control group (n = 25) that did not participate in any exercise. The data were evaluated using the Wilcoxon Signed Rank test and the Mann–Whitney test. After five days of exercise, a notable decrease in blood pressure occurred in the intervention group, both for prehypertension (systolic p < 0.001; diastolic p = 0.005) and stage 1 hypertension (systolic p = 0.003; diastolic p = 0.012). No remarkable changes were noted in the control group (p > 0.05). The comparison between the two groups indicated significant differences in blood pressure changes for both categories (p < 0.05). Isometric handgrip training significantly affects reducing blood pressure in individuals with prehypertension and stage one hypertension.
