Abstract

Lack of sexual knowledge and increasing negative sexual attitudes in Indonesia could lead to risky sexual behavior. This problem increases teenage pregnancy, sexually transmitted infections, and abortion among adolescents. This study aimed to determine the relationship between sexual knowledge and sexual attitudes towards sexual behavior among junior high school students in West Jakarta. This study was cross-sectional, conducted on 544 junior high school students in West Jakarta. Measuring instruments used were characteristic questionnaires, sexual knowledge questionnaires, sexual attitude questionnaires, and sexual behavior questionnaires. Data analysis was performed using bivariate (chi-square). This study shows 79.2% of the respondents had low sexual knowledge, 45.6% respondents had negative sexual behavior, and 48.2% respondents had risky sexual behavior. This study finds that most male respondents had low sexual knowledge (80.8%), low sexual attitude (56.8%), and “less-safe” risky sexual behavior (60.0%), while “not-safe” risky sexual behavior (2.7%) was found higher in female respondents. Bivariate analysis shows a significant relationship between sexual knowledge (p=0.006; 95% OR=1.763 |95% CI=1.151-2.698) and sexual attitude (p=<0.001; OR=2.852 | 95% CI=2.012-4.043) towards sexual behavior. In conclusion, low sexual knowledge and negative sexual attitudes increase the risk of risky sexual behavior.

Abstract

Background: Diagnosing skin conditions can be challenging in resource-limited settings. Cyanophyceae, or blue-green algae, are found in water bodies worldwide and can lead to harmful algal blooms under specific conditions. East Nusa Tenggara, a province in eastern Indonesia, with its hot, dry climate and pristine waters, creates ideal conditions for these blooms. While dermatitis from Cyanophyceae exposure is rare, the potent biotoxins produced by these algae may cause skin reactions. This case report aimed to describe the dermatitis that was possibly caused by Cyanophyceae. Case description: A 22-year-old male from rural East Nusa Tenggara presented with pruritic papules, pustules, and vesicles on both arms for two days. The lesions began as erythematous papulo-vesicular formations and progressed to oozing and crusting shortly after he cleaned a neglected fish pond with algal blooms. The eruptions were confined to exposed areas of both arms. The patient reported no fever, cough, headache, or throat pain, and other physical findings were normal. After two weeks, the lesions improved significantly with topical mometasone furoate. The patient was educated on proper hand hygiene and avoiding similar allergens. Conclusion: Cyanophyceae can release biotoxins that may cause hypersensitivity reactions on human skin. In addition, the lipopolysaccharides found in their cell walls can also irritate human skin. Skin reactions vary and depend on factors such as individual susceptibility, cyanobacterial profile, toxin types and concentrations, and skin barrier disruption. Cyanophyceae can cause irritation and allergic responses.
