Seroprevalence of influenza A H1N1 (swine) infection in the human population in a cantonment.

BACKGROUND: Various serosurveys and studies were conducted globally on pandemic influenza. H1N1 virus reported so far provides ample evidence of differing perspectives, regarding its epidemiology especially with regard to prevalence, populations groups, and behaviour related to vaccine acceptance. A multigroup, cross-sectional survey among 658 healthy subjects was carried out, in Pune among students, health-care workers (HCWs), and soldiers to assess the seroprevalence of pandemic influenza H1N1 virus and its associated factors. METHODS: The total sample size, based on forecasted prevalence of 33%, worked out to be 640. We studied 658 subjects including 103 students, 201 HCWs, and 354 serving soldiers. The sample for each group was selected from the respective study population by simple random sampling using a random number table. Haemagglutination inhibition test was carried out at the National Institute of Virology. RESULTS: The overall seroprevalence of pandemic influenza H1N1 (2009) virus was found to be 46.5% (95% confidence interval 42.6-50.4) which was adjusted to 39.4% after excluding those vaccinated. The availability of vaccine for high-risk group such as HCWs did not find much favour with the HCWs who did not accept vaccine for various reasons. Whereas only one student was vaccinated, 21.4% of HCWs and 32.5% of soldiers were vaccinated. CONCLUSION: Based on high seroprevalence of antibodies against H1N1 virus during pandemic, vaccination of general population is not recommended. However, high-risk groups and HCWs need to be protected with flu vaccine. There is a need to encourage HCWs for accepting vaccination.

Filaria surveys in the Armed Forces: Need for a revisit.

BACKGROUND: Routine annual filarial surveys are conducted amongst various categories of military personnel and their families as per policies in vogue in the Armed Forces. The neglect and inattention faced by this disease needs to be addressed in terms of policy, provisioning and processes while dealing with filariasis in the Armed Forces. METHODS: Routine annual filarial survey was conducted in a garrison during the months of Nov and Dec in 2013 and 2014. Blood slides from 6305 and 10,162 persons were collected in 2013 and 2014 respectively. 546 (60.66%) civilian migratory labourers were also subjected to the filarial survey. RESULTS: Of the blood slides collected amongst service personnel, 41 were positive for mf in 2013 and 29 in 2014 (i.e. a slide positivity rate (SPR) of 0.65% and 0.28% respectively). Out of 546 blood slides of the migratory population, 10 were found mf positive (SPR 1.83%) and three males had lymphedema. CONCLUSION: It is recommended that routine annual filarial survey conducted in military garrisons should include all personnel belonging to known endemic states. Newer modalities of detection of infection may be considered to replace night blood surveys. An organization-specific surveillance programme on prevention and control of Lymphatic filariasis in the Armed Forces thus may need to be launched so that we can achieve elimination.

Role of dietary habits and personal hygiene on nutritional status of school-going adolescents: A cross-sectional study in selected schools located in slum areas of Nagpur City, Maharashtra.

Purpose: Adolescence is a nutritionally vulnerable time when rapid physical growth increases nutrient demand. Addressing the nutrition needs of adolescents could be an important step toward breaking the vicious cycle of intergenerational malnutrition. Under the healthy school initiative, a baseline assessment was carried out to assess the nutritional status, dietary habits, and personal hygiene of school-going adolescents to plan the future interventions at school level. Materials and Methods: A cross-sectional study was conducted in two government-aided schools for 6 months among 814 students of Class VI-IX to assess their dietary habits and personal hygiene by using the GSHS( Global School based student Health Survey) -2007(Indian version) tool. Anthropometric measurement was taken by standard technique. Results: The study found the proportion of thinness, stunting, and overweight/obesity as 40%, 20%, and 4.2%, respectively. Male students were found more thin (61.1% vs. 38.8%) and stunted (55.6% vs. 44.4%) as compared to female students. Less than one-fourth (13.7%) of the students reported <5 servings of fruits and vegetables. In multivariable analysis, male students, children of homemaker mother, skipping breakfast on all days of week, consumption of fast food ≥3 times/week, consumption of high sugary ready to use food, and infrequent handwashing after toilet were found to be predictors of thinness. Conclusion: Dietary habits and personnel hygiene were found to be important factors of undernutrition; promoting health behavior through school health policy with involvement of teachers, students, and parents is highly recommended to reduce the problem of undernutrition among adolescents.

Résumé Objectif: L'adolescence est une période de vulnérabilité nutritionnelle pendant laquelle une croissance physique rapide augmente la demande en nutriments. Répondre aux besoins nutritionnels des adolescents pourrait constituer une étape importante vers la rupture du cercle vicieux de la malnutrition intergénérationnelle. Dans le cadre de l'initiative pour une école saine, une évaluation de base a été réalisée pour évaluer l'état nutritionnel, les habitudes alimentaires et l'hygiène personnelle des adolescents scolarisés afin de planifier les futures interventions au niveau de l'école. Matériels et Méthodes: Une étude transversale a été menée dans deux écoles subventionnées par le gouvernement pendant 6 mois auprès de 814 élèves des classes VI à IX pour évaluer leurs habitudes alimentaires et leur hygiène personnelle à l'aide du GSHS (Enquête mondiale sur la santé des élèves en milieu scolaire) -2007 (version indienne) outil. La mesure anthropométrique a été prise par la technique standard. Résultats: L'étude a révélé que la proportion de maigreur, de retard de croissance et de surpoids/obésité était de 40 %, 20 % et 4,2 %, respectivement. Les étudiants de sexe masculin se sont révélés plus minces (61,1 % contre 38,8 %) et rabougris (55,6 % contre 44,4 %) que les étudiantes. Moins d'un quart (13,7 %) des élèves ont déclaré <5 portions de fruits et légumes. Dans une analyse multivariée, les étudiants de sexe masculin, les enfants d'une mère au foyer, le fait de sauter le petit-déjeuner tous les jours de la semaine, la consommation de restauration rapide ≥ 3 fois/semaine, la consommation d'aliments prêts à l'emploi riches en sucre et le lavage peu fréquent des mains après la toilette se sont révélés être des prédicteurs de minceur. Conclusion : Les habitudes alimentaires et l'hygiène du personnel se sont révélées être des facteurs importants de dénutrition ; la promotion de comportements sains par le biais d'une politique de santé scolaire avec la participation des enseignants, des élèves et des parents est fortement recommandée pour réduire le problème de la dénutrition chez les adolescents Mots-clés: Adolescent, habitudes alimentaires, hygiène personnelle, dénutrition.
