Abstract

Latar Belakang: Stunting menjadi salah satu isu kesehatan di negara-negara berkembang termasuk Indonesia, dengan prevalensi yang tinggi yaitu 30.8%. Stunting tidak hanya dipengaruhi oleh faktor nutrisi, tetapi juga riwayat kesehatan seperti penyakit infeksi dan lingkungan rumah tangga. Tujuan: Untuk menganalisis hubungan kejadian ISPA dengan stunting dengan memperhitungkan perancu (status gizi ibu saat hamil, riwayat berat bayi lahir, kelengkapan imunisasi anak, riwayat diare dan sumber air minum). Metode: Studi potong lintang ini menerapkan total sampling dari data Riset Kesehatan Dasar (Riskesdas) 2018 oleh Badan Penelitian dan Pengembangan Kesehatan. Hasil: Kejadian ISPA berhubungan dengan stunting (p = 0.029) dengan OR 3.115 (95%CI 1.079-8.994). Namun setelah dikontrol dengan status gizi ibu saat hamil, riwayat berat bayi lahir, kelengkapan imunisasi anak, riwayat diare dan sumber air minum maka ISPA tidak berhubungan bermakna dengan stunting (p > 0.05), meskipun nilai OR tinggi, masing-masing ISPA 3.148 (95%CI 0.592-16.740), untuk diare OR 2.296 (95%CI 0.602-8.759) dan BBLR 2.851 (95%CI 0.772-10.528). Kesimpulan: Kejadian ISPA, diare dan BBLR pada anak berkontribusi terhadap kejadian stunting, masing-masing sebesar 3, 2.8 dan 2.2 kali.

Abstract

COVID-19 medical waste is residual material from unused reuse which is contaminated by substances that protect infectious or in contact with patients and/or hospital staff who need COVID-19 patients from service activities in the emergency room, isolation room, ICU room, treatment rooms, and other service rooms. The purpose of this study was to discover waste treatment in referral hospitals in North Sulawesi Province arising from the implementation of COVID-19 in 2020. The research was conducted on 18 of COVID-19 Referral Hospitals in North Sulawesi Province in period May - June 2020, by using cross-sectional as a research design. The results showed that 11 hospitals (61.1%) treated COVID-19 medical waste using their own incinerator, while 7 other hospitals (38.9%) treated COVID-19 medical waste using third-party services. All of the hospitals that treat medical waste using an incinerator do not fully have an operational permit from the Ministry of Environment and Forestry. The results obtained, in an emergency (COVID-19 pandemic), are excluded from having permission to use incinerators. All health facilities are expected to carry out the process of arranging incinerator operational permit documents coordinating with the Provincial / Regency / City Health Office and Provincial / Regency / City Environment Offices, even in the COVID-19 pandemic.

Abstract

Activities at the bus station may cause environmental pollution, including noise. High noise levels can cause human health problems, especially hearing loss. This study aims to determine the correlation between noise level and hearing loss of the population around Pakupatan Bus Station. This study used an analytical observational approach with a cross sectional design. The survey was conducted in six residences around Pakupatan Bus Station in Serang City, Banten from January to May 2018. The samples of this study were 100 respondents selected by proportional random sampling technique. The noise level of residents around Pakupatan Bus Station reached 81.09 decibels which exceeded the noise quality standard of 55 decibels in 1996 No. 48 of the Ministry of Environment. The confounding variables included age, sex, health history, type of work, smoking, drinking, and length of stay of the respondents. Type of work and length of stay were the confounding variables of the correlation between noise level and hearing loss. The odd ratio of the type of work was 0.267 and the length of stay was 0.365, so it was necessary to apply green lines or to plant trees. The residents who were exposed to noise >70dB had a risk of 4.673 times higher than the noise level 70dB after being controlled by the variable length of stay and variable work.

Abstract

The COVID-19 pandemic poses a risk of increasing cases of computer vision syndrome (CVS) due to changes in the environment for work and study because of the implementation of the Work/Study from Home policy. This study aimed to determine the risk factors associated with CVS in students. The study design was cross-sectional with the population of bachelor program students, with a sample size of 124 students. Data were collected through online questionnaires. Data analysis was carried out to study the statistical relationship between the independent variables and the dependent variable using the Chi-Square test. This study showed that the prevalence of CVS among students was 87.1%. The analysis showed that one variable had a significant relationship with CVS in students, namely emotional exhaustion (OR 5.47, 95% CI: 1.75-17.02). Another variable, although not significant, was considered to play a role as a risk factor for CVS, namely the duration of computer use (OR 4.75, 95% CI: 1.02-22.25). Emotional exhaustion and duration of computer use are important risk factors in the occurrence of CVS in students during the online learning period. It is necessary to increase socialization regarding the ergonomics of using computers and stress management to prevent CVS in students.
