Backgroud. Adolescence is a vital part of child development, where acquired eating/dietary behaviour is often associated with ones’ perception of body shape. Objectives. To assess eating habits in relation to body shape perception and esteem in middle-school (junior-high) pupils. Materials and Methods. Surveyed subjects were 170 middle-school pupils from Warsaw; 101 girls and 69 boys aged 15 years. An anonymous questionnaire was used to determine eating habits, body mass, growth and body shape perception. Anthropometric measurement cut-off points were taken according to the method of Cole et al. Results. Only 29% of pupils ate 5 daily meals; of whom there were significantly more girls than boys (35% vs 20%, p = 0.042). Girls more often consumed second breakfast than boys (p < 0.001), whilst boys ate dinner more frequently than girls (p = 0.004). Eating meals was observed in 86% all pupils, where sweets (71%) and fresh fruit (69%) were most commonly eaten. Boys ate fast-food more often than girls (p = 0.004), as well as savoury snacks (p = 0.002), sweets (p = 0.009) and sweetened fizzy drinks (p < 0.001). Girls however, consumed more low-fat foodstuffs compared to boys (p = 0.003). Overweight was more common in boys than girls (26% vs 9%, p = 0.003), whereas girls were more frequently malnourished than boys (21% vs 7%, p = 0.016). Far fewer girls were satisfied with their body shape compared to boys (51% vs 94%, p <0.001). Girls also more commonly expressed a desire for slimming, despite either having a correct body mass or being underweight. Conclusions. Many adverse and abnormal eating habits of pupils were found, especially in boys, that could lead to overweight and obesity. Subjects were found to incorrectly assess their body shape, particularly the girls, thereby leading to unwarranted slimming behaviour.
Caligus serratus Shiino, 1965 (Copepoda: Caligidae), a parasite on 11 fish species caught in Chamela Bay off the Pacific Coast of Mexico, is redescribed based on material found on Pacific agujon needlefish Tylosurus pacificus (Steindachner, 1876). Caligus serratus can be distinguished from its congeners by the combination of the following characters: i) short abdomen (approximately 0.2 times as long as cephalothorax), ii) pointed posteromedial process on the first segment of the antenna, iii) sternal furca with bluntly pointed, diverging tines, and iv) leg 4 exopod bearing 3 unequal, distal spines (the shortest 0.2 times the length of the longest). Microphotographs of female and illustrations of both female and male are provided. The redescription of this species might be useful given its low host specificity.
First instar male and female of Quadraspidiotus zonatus (Frauenfeld) are described and illustrated; dorsal tarsal campaniform sensillum is present in male, absent in female. Some biological date are given.
Maritrema formicae sp. nov. is described from the Patagonian coast, Argentina, based on adults obtained from the kelp gull, Larus dominicanus. The new species fits with the “eroliae complex” and can be distinguished from other related species mainly in shape and size of body, shape, size, and pattern of distribution of cirrus spines, uterus extension, number and size of eggs, vitellarium in a complete ring in all specimens, and its Neotropical distribution. The new species is sympatric with another species of the genus, Maritrema madrynense, which was recorded in the same host and locality.
