Population structure and seasonal dynamics of mosquitoes in different types of residential areas / 中国血吸虫病防治杂志

Objective To investigate the effect of the type of neighborhoods on the population structure and dynamics of mos-quitoes. Methods The adult population dynamics and larvae breeding of mosquitoes in four different types of neighborhoods were investigated in Yangzhou City. Results The number of trapped mosquitoes was the largest in the urban villages,and more than 800 adult mosquitoes were trapped in each urban village,which was significantly higher than that of ordinary and high qual-ity residences. Aedes albopictus and Culex pipiens pallens were dominant species(D>10％)in the four types of residential ar-eas,and Ae. albopictus was the most dominant species(D>57％). The peak occurrence of Ae. albopictus in different areas oc-curred in early June,and it occurred again in the urban village in the middle of September. The occurrence quantity of Cx. pipi-ens pallens was stable in the ordinary residence and high quality residence,while in the urban village and resettlement residen-tial area,the peak occurred in mid-October. The orders of positive rates,densities and the numbers of mosquitoes in the differ-ent types of residential areas were:the urban villages>the resettlement residence>the ordinary residence>the high quality resi-dence. The water vat had the highest positive rate in all kinds of larval habitats,followed by tires and green belt with garbage wa-ter. Conclusions The main mosquito species in the four different types of residential areas are all Ae. albopictus and Cx. pipiens pallens,but the positive rate,density and the number of mosquitoes in the different types significantly change,especially in the urban villages,the number and the occurrence peak are significant different from those in the other types of residential areas.

Preference and the Frequency of Processed Food Intake according to the Type of Residence of College Students in Korea / 대한지역사회영양학회지

OBJECTIVES: The purpose of this study was to investigate the eating behavior toward processed foods among college students who live in different types of residence. METHODS: This is a cross-sectional study targeting a total of 476 college students living at home with their family, living in a rental house with self-boarding, living in a lodging house, and living in a dormitory. Eating behaviors, including preference and the frequency of processed food intake were surveyed and compared according to the type of residence. RESULTS: The rate of skipping a meal was significantly higher among students who reported self-boarding than those living in other types of residences. The main reason for skipping meals was that they got up late. In the entire study population, the main reason for consuming processed food was easy-to-cook (33.8%) and the primary consideration for choosing processed food was the price (54.0%). The processed food the most favored by college students was the processed noodles; those living at home with their family or living in a dormitory preferred milk products; those living in a rental house with self-boarding or in a lodging house preferred confectionery, retort pouch, convenience food, and canned/bottled food. The frequency of processed food intake was significantly higher in the students who reported self-boarding than those living in other types of residences (p < 0.001). CONCLUSIONS: Students' preference toward processed foods differed according to their type of residence. The frequency of processed food intake was significantly higher in students who reported self-boarding indicating that the type of residence of student is associated with their choices and consumption of processed foods.

Study on Dietary Habits of College Women according to the Residence Type in Seoul

This study was designed to compare the dietary habits of women's university students according to residence type. The subjects were 140 females divided into four groups. The first group consisted of students residing at home with their parents (home, n=39), the second group consisted of students residing in a dormitory (dormitory, n=34), the third group consisted of students residing in a boarding house (boarding, n=36), and the fourth group consisted of self-boarding students (self-boarding, n=31). The average age was 21.9 years, and the BMI levels of the groups were 20.8 kg/m2, 19.6 kg/m2, 20.5 kg/m2, and 19.7 kg/m2, respectively. The 'home' group had higher dietary regularity than the other groups (P<0.05). The boarding group and self-boarding group were more likely to eat out and skip breakfast than the home and dormitory groups (P<0.05). All groups indicated that frequency of snacking was higher than 1 time per day, but there was no significant difference between the groups. The dormitory and boarding groups spent less time consuming meals than the other groups. In conclusion, women's university students show different dietary behaviors according to residence type. Especially, the dormitory, boarding, and self-boarding groups need to improve their dietary habits through high quality education and nutritional support at college cafeterias.

A Study on Lifestyles, Dietary Habits, Nutrition Knowledge and Dietary behaviors of Male University Students According to Residence Type / 대한지역사회영양학회지

For the purposes of participation in research projects, living in a laboratory has become popular among male university students who tend to have less opportunity for nutrition education and overestimate their own health, suggesting possibilities of many undesirable practices of lifestyle and dietary habits. Therefore, this study was conducted to investigate and compare health-related lifestyle practices, dietary habits, nutrition knowledge, food preference and dietary behaviors of the male university students according to residence type. The subjects were 260 (34, 15, 44, and 167, respectively for lab-living, self-boarding, dormitory and commuting) male engineering majors in the Gyeonggi area. Self-administered questionnaires consisted of general characteristics, health-related lifestyle practices, dietary habits, fast food consumption, nutrition knowledge, preference for foods and tastes, and selfexamination of dietary behaviors. Lab-living subjects showed many undesirable practices, particularly with more smokers (p < 0.05), irregular eating (p < 0.01), overeating (p < 0.05) and skipping breakfast (p < 0.01), compared to the dormitory students and more time in computer/TV usage (p < 0.05), overeating (p < 0.05), more frequent use of fastfood (p < 0.05), less nutrition knowledge (p < 0.01) and less intake of milk/dairy products (p < 0.01) and fruits (p < 0.01), compared to commuting subjects. More smokers (p < 0.05) and irregular (p < 0.01) and unrelaxed meal times (p < 0.05), compared to the dormitory group, and less intake of fruits (p < 0.01) and dietary fiber (p < 0.01), compared to the commuting group were shown as undesirable practices of the self-boarding group. Therefore, continuous effort should be made to correct undesirable health- and diet-related practices found in this study in order to improve nutritional status as well as general health by developing a nutrition education program and contents of lectures focusing on more specific problems according to each subgroup such as lab-living and self-boarding male university students.
