Hipertensi merupakan salah satu kondisi medis yang cukup serius karena dapat meningkatkan risiko penyakit jantung, otak, ginjal dan penyakit lainnya. Wilayah di DKI Jakarta dengan prevalensi hipertensi tertinggi berdasarkan diagnosis dokter yaitu Kota Jakarta Pusat sebesar 12,16%. Partikulat meter organik dan komponen partikulat meter dapat memicu proinflammatory effects pada paru-paru karena kemampuannya mengakibatkan stress oksidatif. Penelitian ini bertujuan untuk menyusun model pengaruh pajanan PM2,5 di udara ambien terhadap kejadian hipertensi melalui stress oksidatif dan sitokin inflamasi pada penduduk di Jakarta Pusat. Penelitian dilakukan pada penduduk dewasa (18-65 tahun) di Kota Jakarta Pusat dengan disain studi hybrid cross sectional ecology. Pengumpulan data secara cluster random sampling dengan analisis data dilakukan melalui pemodelan regresi logistik multilevel dan cox regresi proporsional hazard.
Hasil analisis menunjukkan terdapat asosiasi antara PM2,5 di udara ambien dengan biomarker stress oksidatif (IOR PM2,5: 2,185173-2,185176) dan dengan biomarker sitokin inflamasi (IOR PM2,5: 1,21-1,91). Pemodelan multivariat dengan cox regresi proporsional hazard menunjukkan bahwa variabel umur dan indeks massa tubuh merupakan confounder hubungan antara stress oksidatif dengan hipertensi dan antara sitokin inflamasi dengan hipertensi dengan nilai Rasio Prevalens adjusted (95% CI) masing-masing sebesar 1,19 (0,69-2,03) dan 0,99 (0,58-1,72). Dapat disimpulkan bahwa variabel konsentrasi PM2,5 di udara ambien memiliki peran terhadap terjadinya hipertensi, stress oksidatif dan sitokin inflamasi pada penduduk di Jakarta Pusat.
Hypertension is a serious medical condition that can increase the risk of heart, brain, kidney and other diseases. The area in DKI Jakarta with the highest prevalence of hypertension based on doctor diagnosis is Central Jakarta city about 12.16%. Organic particulate matters and particulate matter components can trigger proinflammatory efects in the lung due to their ability to cause oxidative stress. This study aims to develop a model of the Influence of PM2,5 Exposure in Ambient Air on Hypertension Occurrence through Oxidative Stress and Inflammatory Cytokines among residents in Central Jakarta. The study was conducted among adult residents (age 18-65 years) in Central Jakarta with hybrid cross sectional study design. Data collected using cluster random sampling with data analysis carried out through multilevel logistic regression modeling and cox proportional hazard regression. Results show there is an association between PM2.5 in ambient air with oxidative stress biomarkers (IOR PM2.5: 2.185173-2.185176) and with inflammatory cytokine biomarkers (IOR PM2.5: 1.21-1.91). Multivariate modeling with Cox regression proportional hazard shows that age and body mass index are confounders of the relationship between oxidative stress with hypertension and between inflammatory cytokines with hypertension with an adjusted prevalence ratio (95% CI) value of 1.19 (0.69-2.03) and 0.99 (0.58-1.72). It can conclude that concentration of PM2.5 in ambient air has a role on hypertension, oxidative stress and inflammatory cytokine among residents in Central Jakarta.
This thesis discusses the relationship between PM2.5 exposure concentrations and MDA levels as biomarkers of oxidative stress in the environment of a cement factory. This research is a quantitative study with a cross-sectional design conducted in May-June 2024. The results of the research show that the PM2.5 concentration from all 10 points exceeds the quality standard; urine MDA level examination results vary; there was no significant relationship between exposure to PM2.5 concentrations and urinary MDA levels; there was no significant relationship between individual characteristics and urinary MDA levels; However, there is a significant relationship between PM2..5 concentration and radius with a p value of 0.000; there is a significant relationship between PM2.5 concentration and sampling time with a p value of 0.000; and there is a significant relationship between MDA levels and radius with a p value of 0.000. The research conclusion shows that there is no relationship between PM2.5 exposure and MDA levels, there is no relationship between individual characteristics and MDA levels.
Benzene can be enzymatically increasing the formation of Reactive OxygenSpecies (ROS) that affect the cells and cause oxidative damage. Malondialdehyde(MDA) is the end product of lipid peroxidation and is one indicator of oxidativestress caused by free radicals. S-phenylmercapturic acid (SPMA) be the parameterof benzene exposure in humans. This study aimed to analyze the associationSPMA against MDA in shoe workers. The research method uses design analyticcross-sectional study. Selection of the sample using one level cluster to informalindustry. The samples in this study are 64 workers. The results showed thatmedian levels concentration of SPMA is 10.24 mg/g creatinine or 20 respondents(31.2%) had a concentration of SPMA urine above the value of biologicalexposure index (BEI) (> 25 mg / g creatinine), and median levels of serum MDAworkers are 6.38 μmol/L. Based on statistical test, we know that have a significantassociation for concentration of SPMA to increase MDA after controlling by age,length of employment, smoking status, alcohol habits, exercise habits and habit ofeating vegetables and fruits (R2: 0133, p-value: 0.039). This study shows thatexposure to benzene giving adverse effects on oxidative stress in addition toworkers by age workers.Keywords: Benzene; Small Scale Industry; Malondialdehyde; Oxidative Stress;S-phenylmercapturic acid;
500 mg with Vitamin E 200 mg to Decrease Oxidative Stress and Increase Antioxidant on Technician Crew Military Aircraft. Oxidative stress is pathological condition body that is caused by imbalance between oxidants with antioxidants body, which produces free radicals that can lead cell damage early. Free radical will bind building blocks cell covering of fat, protein and DNA will result damage cell, so cell can not regenerate that affect onset of degenerative diseases. Technicians crew military aircraft as specialized personnel with activity job direct contact with material oxidant, thus high risk of oxidative stress. Vitamin C and vitamin E are antioxidant enzyme exogen outside body which has role inhibiting oxidative stress, so oxidative stress does not occur. The design study experimental studies with intervention randomized double blind controled trial. Sample size 206 people divided into two groups are intervention group with sample size 103 people are given supplements combination vitamin C 500 mg with vitamin E 200 mg and control group with sample size 103 people are given placebo for 40 days without break. Data collected include are characteristics of respondent, pattern and amount of consumption of vitamin C, vitamin E and nutrient food, derived from food frequecy questionnaire (FFQ) and 24-hour recall, examination of oxidative stress by checking levels malondialdehyde (MDA) and examination of antioxidant by checking levels glutathione (GSH) in blood serum in pre and post intervention. The results showed decrease oxidative stress in group intervention who are received suplement combination vitamin C 500 mg with vitamin E 200 mg compared with control group who are received placebo, are significant with p value 0.04 with effects size -0.089 nmol/mL, confidence interval 95 % (-0.17875 - 0.00095). No increase antioxidants in group intervention who are received supplement combination vitamin C 500 mg with vitamin E 200 mg compared with control group who are received placebo, are not significant with p value 0.81 with effects size -0.019 ug/mL, 95% confidence interval ( -0.140 - 0.180).
