Catholic Parish Priests and Birth Control: A Comparative Study of Opinion in Colombia, the United States, and the Netherlands

Studies in Family Planning (1971)

Gail Anne Shea Thomas K. Burch Gustavo A. Esguerra Miriam Ordonez Joseph Van Kemanade

There is a lack of knowledge concerning attitudes and opinions of parish priests concerning birth control. This exploratory study was undertaken to fill this gap; findings are based on sample survey data of 500 parish priests in Colombia 1711 in the U.S. and 1500 in the Netherlands. Essentially the same questions were asked in all 3 countries. Mail questionnaires were used in the Netherlands and the U.S. Interviewers completed the questionnaire in Colombia. The study indicates that Catholic priests in all 3 countries overwhelmingly accept the idea of family limitation as necessary. Their personal views on the morality of specific birth control methods differ widely depending on the specific method. Their collective opinion revealed significant differences from official teaching particularly in the Netherlands. In Colombia and the U.S. the priests are strongly divided in their opinions. More than 2/3 of the priests in Colombia and the U.S. believed that use of contraceptives leads to a general decline in moral standards; however the Dutch priests are less inclined to have this opinion. Regarding Pope Paul VIs continued ban on contraception 1/3 of the parish priests in Colombia disagree with it and 1/2 of the priests in the U.S. are in disagreement. In the Netherlands the priests and bishops are almost unanimous in their acceptance of contraception. There is definitely a difference of opinion concerning these issues among the Catholic communities of different countries. It appears that the situation is moving toward greater permissiveness in church teaching on contraception. This change appears to be due to the fact that the younger priests are already more permissive than their elders and that this is the trend in the secular culture.

OBSERVATIONS ON THE OXYGEN SUPPLY TO THE FETAL LLAMA

Quarterly Journal of Experimental Physiology and Cognate Medical Sciences (1960)

Giacomo Meschia Donald H. Barron Harry Prystowsky André E. Hellegers William E. Huckabee

The oxygen dissociation curves of the maternal and fetal bloods of the llama show a high saturation at low oxygen pressures. At 38° C. and p H 7·4 the maternal blood is half saturated with an oxygen pressure of 21·9 mm. Hg, the fetal at 18·0. The data about the adult animal confirm the previous results of Hall, Dill and Guzman Barron. The estimated transplacental difference in oxygen pressures of the two bloods in vivo was about 15 mm. Hg. As the llama has a six‐layered epithelio‐chorial placenta, the hypothesis that the thicker placental types are necessarily associated with steep transplacental gradients in oxygen pressure appears to be without foundation.

EFFECTS OF OSMOTIC GRADIENTS ACROSS THE PRIMATE PLACENTAL UPON FETAL AND PLACENTAL WATER CONTENTS

PEDIATRICS (1964)

Paul D. Bruns André E. Hellegers A. Elmore Seeds Richard E. Behrman Frederick C. Battaglia

Infusions of 2.7 g/100 ml sodium chloride or 30 g/100 ml disaccharide solutions into the maternal circulation of pregnant rhesus monkeys produced a significant reduction in fetal and placental total water content. At the same time large transplacental total solute concentration gradients were produced. The injection of sucrose into the amniotic fluid of pregnant rhesus monkeys produced a reduction in fetal total body water alone. The significance of these differences is discussed.
