Medina 3 ABSTRACT Hurricanes and other natural disasters can produce crop destruction, population displace- ment, infrastructure damage, and long-term public health consequences that include increased malnutrition among the affected populations. This paper presents the results of anthropomet- ric measurements taken of 295 children under 5 years of age from three regions of Honduras that were affected by Hurricane Mitch, a major storm that struck Central America in the fall of 1998. The children in our study were sampled in three shelters in the capital city of Tegu- cigalpa; in the resettlement zone of Nueva Choluteca, Choluteca; and in the small urban area of Catacamas, Olancho. Our data indicated that, in comparison to the period before the hurri- cane, there was an elevated prevalence of wasting in all three of the study areas, and that there were also high levels of underweight in the Tegucigalpa and Nueva Choluteca study areas. There were statistically significant differences between the mean values of malnutrition indi- cators for Catacamas and those for the Tegucigalpa and Nueva Choluteca settlements. These differences suggest that resettled families were confronting a nutritional crisis in July and Au- gust of 1999, some 9 months after the hurricane struck.

RESUMEN Los huracanes y otros desastres naturales pueden destruir cosechas, desplazar a pobla- ciones enteras, causar daños infraestructurales y acarrear consecuencias a largo plazo para la salud pública, entre ellas un aumento de la desnutrición en las poblaciones Estado nutricional de niños afectadas. Este trabajo presenta los resultados de las mediciones antropométricas de menores de 5 años 295 niños menores de 5 años de tres zonas de Honduras que fueron azotadas por en tres zona de Honduras el huracán Mitch, tempestad que azotó Centroamérica en el otoño de 1998. Los niños que participaron en nuestro estudio provinieron de tres alojamientos provisiona- azotadas por un huracán les, uno en la capital del país, Tegucigalpa; otro en la zona de asentamiento para refu- giados de Nueva Choluteca, Choluteca; y otro en la pequeña zona urbana de Catacamas, Olancho. Según indican nuestros datos, en comparación con el período anterior al huracán, la frecuencia de emaciación en las tres zonas fue alta, como tam- bién lo fue la de peso subnormal en las zonas de estudio de Tegucigalpa y Nueva Choluteca. Hubo diferencias estadísticamente significativas entre los valores prome- dio de los indicadores de desnutrición en Catacamas y los de los asentamientos de Tegucigalpa y Nueva Choluteca. Estas diferencias indican que las familias desplazadas enfrentaban una crisis nutricional en julio y agosto de 1999, alrededor de 9 meses des- pués de la llegada del huracán. Recent sociocultural change will raise the probability of incongruity between the culture of the migrant and the social situation in which he lives. Such incongruities as occur will place excessive adjustive burdens on the social groups in which the migrant interacts and on the personality system of individual migrants. Insofar as these stresses are not absorbed by the small group systems and/or the personal- ity system, recent migrants to an industrial milieu are likely to manifest increased rates of psychological, somatic, and social ill health. [Los recientes cambios socioculturales aumentarán la probabilidad de discrepan- cias entre la cultura del emigrante y el medio social en el que vive. Tales discre- pancias impondrán cargas de adaptación excesivas a los grupos sociales con los que interactúa el emigrante y a su personalidad individual. En la medida en que estas dificultades no son asimiladas por el sistema del grupo social inmediato y la personalidad, es muy probable que se produzca un aumento en las tasas de trastornos psicológicos, somáticos y sociales entre las personas que acaban de migrar a un ambiente industrial.] John Cassel and Herman A.
