Women's experiences of giving birth after 35.

BACKGROUND: This research forms part of a longitudinal study comparing experiences of pregnancy, birth, and the first year of motherhood among women aged 35 years and over with women aged 20 to 29 years, in the light of the current trend toward later childbearing. METHODS: Data from 107 women were collected from medical records of labor and delivery, and women themselves evaluated control and pain management in labor, satisfaction with support from professionals, labor problems, and postnatal depression. Associations between maternal age and parity and 1) obstetric outcomes, 2) women's perceptions of labor and delivery, and 3) postnatal depression were calculated. RESULTS: Professionals were more likely to place women over 35 years than those aged 20 to 29 years in a "high-risk" category, but medical records of labor and delivery revealed few maternal age effects. Older mothers were more likely than younger mothers to acknowledge that their baby's life might have been at risk during labor, and that they felt happy about the way staff managed labor problems. They were less likely than younger mothers to blame others for making labor pain worse. CONCLUSIONS: Older and younger women's experiences of labor differed in ways that were not mirrored by obstetric differences. Women over 35 years, even if healthy, may believe that their age makes their infants particularly vulnerable during labor. Their higher levels of concern do not necessarily have negative consequences for their experience of childbirth or for their postnatal emotional well-being.

Guinea-pig vocalizations: their structure, causation and function.

A colony of approximately 150 adult and infant guinea-pigs was studied in order to investigate the structure, causation and function of guinea-pig vocalizations. Behaviour and sound recording were made in a wide variety of contexts and sounds were analysed on the Kay Electric Sonagraph 6061 B. Sonagrams were measured, and on the basis of physical structure alone, 11 call types were distinguished. Behavioural records were examined and it was suggested that 5 functional categories existed. The significance of vocal communication in guinea-pig social behaviour was discussed.

Pet owner attitudes to pets and people: a psychological study.

A preliminary attempt was made to assess how pet owners view their relationships with their pets and how pet relationships compare with human relationships. In the sample studied there was a marked variation between individuals in their perceptions but two group trends emerged. First, the pet relationship was most similar to the relationship to the individual's own child and, secondly, the pet relationship was frequently valued because of the attributes of 'dependency', 'fun/play' and 'relaxation based on absence of demands'. It is suggested that the personal meaning of pets for people needs to be further explored.
