Metformin Versus Insulin for Gestational Diabetes: Cognitive and Neuropsychological Profiles of Children Aged 9 years

OBJECTIVE

We compared cognitive profile and neuropsychological performance in 9-year-old offspring of mothers who were treated with metformin or insulin for gestational diabetes mellitus (GDM).

METHODS

A total of 172 children whose mothers were randomly assigned to receive either metformin or insulin for GDM were studied at the age of 9 years. Of these children, 127 were from Turku, Finland (63 metformin and 64 insulin), and 45 from Oulu, Finland (19 metformin and 26 insulin). Clinical and demographic background characteristics were obtained at enrolment, birth, and 9-year follow-up. Cognitive profiles were examined at age 9 years with the Wechsler Intelligence Scale for Children. Neuropsychological functions were examined with 2 subtests of the Developmental Neuropsychological Assessment test battery assessing comprehension of instructions and narrative memory, Trail Making Test assessing attention and with Behavioral Rating Inventory of Executive Functioning, including parent-rated and teacher-rated evaluations. Academic functioning was studied with reading fluency subtest of the Screening test for reading, writing, and calculus for first to sixth grades and information about educational support received at school reported by parents.

RESULTS

The cognitive profiles, including indexes of verbal comprehension, perceptual reasoning, working memory, and processing speed, did not differ significantly between metformin-treated and insulin-treated groups. Significant differences were not found between the treatment groups in assessed neuropsychological functions, reading fluency, or received level of support at school.

CONCLUSION

Cognitive and neuropsychological outcomes were similar in 9-year-old children whose mothers had either metformin or insulin treatment of GDM.

Metformin versus insulin for gestational diabetes: Adiposity variables and adipocytokines in offspring at age of 9 years

AIMS

To compare body composition, visceral adiposity, adipocytokines, and low-grade inflammation markers in prepubertal offspring of mothers who were treated with metformin or insulin for gestational diabetes mellitus (GDM).

METHODS

172 offspring of 311 mothers randomized to receive metformin (n=82) or insulin (n=90) for GDMwere studied at 9 years of age (follow-up rate 55%). Measurements included anthropometrics, adipocytokines, markers of the low-grade inflammation, abdominal magnetic resonance imaging (MRI), magnetic liver spectrometry (MRS), and whole body dual-energy X-ray absorptiometry (DXA).

RESULTS

Serum markers of low-grade inflammation, visceral adipose tissue volume, total fat percentage, and liver fat percentage were similar between the study groups. Serum adiponectin concentration was higher in children in the metformin group compared to insulin group (median 10.37 vs 9.50 µg/ml, p = 0.016). This difference between groups was observed in boys only (median 12.13 vs 7.50 µg/ml, p<0.001). Leptin/adiponectin-ratio was lower in boys in the metformin group than in the insulin group (median 0.30 vs 0.75; p = 0.016).

CONCLUSIONS

Maternal metformin treatment for GDM had no effects on adiposity, body composition, liver fat, or inflammation markers in prepubertal offspring compared to maternal insulin treatment but was associated with higher adiponectin concentration and lower leptin/adiponectin-ratio in boys.

Prediction of pre-diabetes and type 2 diabetes nine years postpartum using serum metabolome in pregnant women with gestational diabetes requiring pharmacological treatment

AIMS

We examined the association between serum metabolome in women with pharmacologically treated gestational diabetes (GDM) and measures of glucose metabolism 9 years postpartum.

METHODS

Serum targeted metabolome, adiponectin, inflammatory markers, and insulin-like growth factor-binding protein-1 phosphoisoforms were analyzed at the time of diagnosing GDM. Glucose metabolism and insulin resistance were assessed at 9 years postpartum. Data from 119 subjects were available for analyses. Associations between baseline measures and future measures of glycemia were examined with univariate regressions and multivariate prediction models. This is a secondary analysis of a previous prospective trial (NCT02417090).

RESULTS

Baseline serum markers were most strongly related to measures of insulin resistance at 9-years follow-up. In multivariate analyses combination of IDL cholesterol, early gestational weight gain and in oral glucose tolerance test fasting and 2-h glucose predicted development of disorders of glucose metabolism (pre-diabetes and/or type 2 diabetes) better than clinical predictors alone (ROC-AUC 0.75 vs. 0.65, p = 0.020).

CONCLUSIONS

Serum metabolome in pregnancy in women with GDM is related to future glucose metabolism and insulin resistance. Compared to clinical variables alone metabolome might result in better prediction of future disorders of glucose metabolism and could facilitate personalized risk stratification for postpartum interventions and follow-up.

A Pan-European Review of Good Practices in Early Intervention Safeguarding Practice with Children, Young People and Families: Evidence Gathering to Inform a Multi-disciplinary Training Programme (the ERICA Project) in Preventing Child Abuse and Neglect in Seven European Countries

Child maltreatment has detrimental social and health effects for individuals, families and communities. The ERICA project is a pan-European training programme that equips non-specialist threshold practitioners with knowledge and skills to prevent and detect child maltreatment. This paper describes and presents the findings of a rapid review of good practice examples across seven participating countries including local services, programmes and risk assessment tools used in the detection and prevention of child maltreatment in the family. Learning was applied to the development of the generic training project. A template for mapping the good practice examples was collaboratively developed by the seven participating partner countries. A descriptive data analysis was undertaken organised by an a priori analysis framework. Examples were organised into three areas: programmes tackling child abuse and neglect, local practices in assessment and referral, risk assessment tools. Key findings were identified using a thematic approach. Seventy-two good practice examples were identified and categorised according to area, subcategory and number. A typology was developed as follows: legislative frameworks, child health promotion programmes, national guidance on child maltreatment, local practice guidance, risk assessment tools, local support services, early intervention programmes, telephone or internet-based support services, COVID-19 related good practices. Improved integration of guidance into practice and professional training in child development were highlighted as overarching needs. The impact of COVID-19 on safeguarding issues was apparent. The ERICA training programme formally responded to the learning identified in this international good practice review.

Comparison of glucose metabolism and anthropometry in women with previous gestational diabetes treated with metformin vs. insulin: 9-year follow-up of two randomized trials

INTRODUCTION

The main aim was to study whether the long-term incidences of type 2 diabetes, pre-diabetes and metabolic syndrome differed between women who were treated with metformin or insulin for gestational diabetes.

MATERIAL AND METHODS

This 9-year follow-up study of two open-label randomized trials compares metformin and insulin treatments of gestational diabetes. In all, 165 women, 88 previously treated with insulin and 77 treated with metformin in the index pregnancy, were included in the analyses. An oral glucose tolerance test was performed, and measures of anthropometry, glucose metabolism, serum lipids and inflammatory markers were compared between the treatment groups. Disorders of glucose metabolism (pre-diabetes and type 2 diabetes) at the 9-year follow-up was the primary outcome of this study. This study was registered at ClinicalTrials.gov: NCT02417090.

RESULTS

The incidences of pre-diabetes and type 2 diabetes (40.3% vs. 46.6%, odds ratio [OR] 0.77, 95% CI 0.40-1.50, p = 0.51), type 2 diabetes (14.3% vs. 15.9%, OR 0.88, 95% CI 0.34-2.26, p = 0.94), pre-diabetes (26.0% vs. 30.7%, OR 0.79, 95% CI 0.38-1.65, p = 0.62), and metabolic syndrome (45.9% vs. 55.2%, OR 0.69, 95% CI 0.35-1.35, p = 0.31) were comparable between the metformin and insulin groups. Moreover, there were no evident differences in the individual measures of anthropometry, glucose metabolism including HOMA-insulin resistance, serum lipids or inflammatory markers between the two treatment groups.

CONCLUSIONS

Treatment of gestational diabetes with metformin vs. insulin during pregnancy is unlikely to have diverging long-term effects on maternal anthropometry, glucose metabolism or serum lipids. From this perspective, both treatments may be considered in gestational diabetes.

Metformin versus insulin therapy for gestational diabetes: Effects on offspring anthropometrics and metabolism at the age of 9 years: A follow-up study of two open-label, randomized controlled trials

AIMS

To compare anthropometrics, and lipid and glucose metabolism in the 9-year-old offspring of mothers treated with metformin or insulin for gestational diabetes mellitus (GDM).

MATERIALS AND METHODS

This was a Finnish two-centre, 9-year follow-up study of two open-label, randomized controlled trials comparing the effects observed in the offspring of mothers who received metformin and insulin treatment for GDM. Measurements included anthropometrics, blood pressure, lipoproteins, and oral glucose tolerance tests. This study was registered with ClinicalTrials.gov, number NCT02417090.

RESULTS

At the age of 9 years 172 children (55% of the original study cohort, 82 from the metformin and 90 from the insulin group) participated in the study. No differences were found between the 9-year-old offspring groups in anthropometric variables, including body mass index and waist-to-height ratio. The offspring in the metformin group had higher high-density lipoprotein (HDL) cholesterol concentrations (1.72 vs. 1.54 mmol/L; P = 0.039) but lower low-density lipoprotein cholesterol (2.39 vs. 2.58 mmol/L; P = 0.046) and apolipoprotein B concentrations (0.63 vs. 0.67 g/L; P = 0.043) than the offspring in the insulin group. The difference in HDL cholesterol concentration was found to be significant only in boys (P = 0.003). The 2-hour glucose value in the oral glucose tolerance test was 0.6-mmol/L lower in boys from the metformin group than in those from the insulin group (P = 0.015).

CONCLUSIONS

Metformin treatment for GDM is associated with similar offspring growth and glucose metabolism but a more favourable lipid profile at the age of 9 years as compared to insulin treatment.

Families' experiences of interaction with the public health nurse at the child health clinic in connection with mother's post-natal depression

The birth of a new family member causes many changes in the way a family functions. Annually some 10% of mothers giving birth suffer from post-natal depression. This depression affects the mother herself, the baby and the functioning of the entire family. The healthcare personnel are faced with an important task in supporting the family in the course of changes occasioned by the birth of a baby. According to earlier studies, families with small children are fairly satisfied with the service provided by the child health clinics. The purpose of the present study was to form a theory of interaction with the public health nurse in the child health clinic when the mother is suffering from post-natal depression from the viewpoint of family. The data for the study were gathered by interviewing nine families (nine mothers and five fathers) where the mother had displayed symptoms of post-natal depression. The data were analysed using continuous comparative analysis of grounded theory. The concepts of the theory emerged as a lack of continuing relationship, a need to be equal partners, a lack of individuality and a lack of family care. The relationships between categories were lack of discussing, lack of being confidential and lack of getting help enough. The core category emerging was lack of holistic cooperation with unique family. In spite of the emphasis placed on family centeredness in the operating principles of the work in child health clinics, its implementation in practical work cannot be taken for granted. Because of the limited resources available to the clinics, it is the experience of depressed mother in particular that they are not treated sufficiently as individuals and that they are subjected to adjudication in the clinics. The parents felt that the personality of the public health nurse was crucial to how they felt about the service they obtained from the clinic.

Intimate partner violence as experienced by men

The purpose of this qualitative, phenomenological study is to describe intimate partner violence as experienced by men and to formulate the common structure of meanings of experiences of men exposed to intimate partner violence. The data were gathered by open-ended interviews with 10 (n = 10) men. The participants had experiences in intimate partner violence. All the 10 men were interviewed twice and they were allowed to tell their experiences as they liked. The data were analysed by applying the method developed by Colaizzi. The experiences of men formulated three main themes describing the factors leading to intimate partner violence, being a victim of intimate partner violence and own violent behavior. The main themes are named as follows: (1) a burden on the pair relationship; (2) face to face with violence; and (3) from denying violence to striving towards the truth. The research results enhance the understanding of the experiences of men. The information may be useful in promoting women's, men's and families' health, developing work on violence and in the education of professionals in social and health care. The results may also help women to understand men's experiences in a pair relationship.

Emotional and informational support for families during their child's illness

PURPOSE

To describe and compare the support provided by nursing staff to families during their child's illness from the viewpoint of families and nurses.

METHOD

A survey method was used. Data were collected by questionnaires planned for families and staff separately. The study population consisted of families who visited paediatric outpatient clinics, families with hospitalized children (n = 344) and the paediatric nursing staff (n = 60).

FINDINGS

Almost half of the families had received adequate emotional and informational support from the nursing staff for their physical and psychological reactions. One-fifth of the families reported that they had not been supported at all during the child's hospitalization. According to families and nurses, the support was provided in the forms of discussion, listening and giving time.

IMPLICATIONS FOR PRACTICE

Families' and nurses' suggestions for development of support were related to the time resources of the staff, to the flow of information, to more client-centred attitudes, to being appreciated and listened to and to home care guidance. However, the pervasiveness of this problem in the international literature suggests that deeper consideration of possible underlying reasons for this phenomenon is called for.

Family dynamics and postnatal depression

Research has shown that postnatal depression (PND) affects 10-15% of mothers in Western societies. PND is not easily identified and therefore it often remains undetected. Untreated depression has a detrimental effect on the mother and child and the entire family. The purpose of this study was to ascertain the state of family dynamics after delivery and whether the mother's PND was associated with family dynamics. The study used a survey covering the catchment area of one Finnish university hospital. Both primi- and multiparas took part and data were collected using the Edinburgh Postnatal Depression Scale (EPDS) for mothers and the Family Dynamics Measure II (FDM II) for both mothers and fathers. The data were analysed using SPSS statistical programme and frequency and percentage distributions, means and standard deviations were examined. Correlations were analysed using Spearman's correlation coefficients. The significance of any differences between mothers' and fathers' scores was determined with a paired t-test. Of the families participating in the study (373 mothers and 314 partners), 13% of the mothers suffered from PND symptoms (EPDS score of 13 or more). As a whole, family dynamics in the families participating in the study were reported to be rather good. However, mothers having depressive symptoms reported more negative family dynamics compared with other families. With the exception of individuation, mothers having depressive symptoms reported more negative family dynamics than their partners. With the exception of role reciprocity, non-depressed mothers reported more positive family dynamics than their partners. Knowledge of the association of mothers' PND with family dynamics could help to develop nursing care at maternity and child welfare clinics and maternity hospitals. Depressed mothers and their families need support to be able to make family dynamics as good as possible.

Interaction between adult patients' family members and nursing staff on a hospital ward

The purpose of this study was to generate knowledge of the interaction between an adult patient's family members and nursing staff from the staff's perspective. Data were collected from nursing staff (n = 155) working on the wards and out-patient departments for pulmonary, rheumatic, neurological and gastroenterological diseases at a university hospital by using a new questionnaire based on earlier research and the literature. The questions explored the staff's views of interaction with the adult patient's family members. In this study, interaction is seen as an umbrella concept which encompasses giving information to relatives, discussion, contacts between staff and significant others and working together. The instrument included questions about personal and telephone discussions, the provision of written instructions and factors facilitating and complicating interaction. The response rate was 55%. The data were analysed using SPSS software and examined using frequency and percentage distributions and cross-tabulation. The open-ended questions were analysed using qualitative content analysis by reducing, grouping and abstracting the data inductively. Discussions with relatives while they visited the patient in hospital were the commonest form of interaction. The majority of respondents perceived the interaction with the patient and knowing his or her family members as important. Less than one-fourth of the respondents started discussion with family members, while the majority expected family members to initiate interaction. The majority of respondents perceived the patient's presence in discussion as important, but sometimes they thought it was necessary to discuss with family members without the patient. The staff discussed with family members mainly in the ward office or in patient rooms, which were, however, not perceived as peaceful. Discussions primarily pertained to the patient's condition, discharge from hospital and planning of continued treatment. The majority of respondents reported that the opportunity for discussion offered by staff, the patient's positive attitude towards discussion with the family and family members' own interest facilitated interaction. The staff's haste and shift-work, family members' shyness of approaching the staff and the absence of a peaceful place for discussion serve to complicate interaction. Family members are primarily seen as informants and recipients of information. The staff's ability to recognize the importance of family members to successful patient care is relatively adequate. However, insufficient attention is paid to family members and their need for support.

Methodological issues in interviewing families in family nursing research

AIM OF THE STUDY

The aim of this study is to discuss what methodological problems can be met in family research with one family member as an interviewee speaking on behalf of the whole family and, vice versa, what is the meaning of having multiple family members or the whole family unit as informants.

BACKGROUND

Family nursing research is part of multidisciplinary research with families. It is a basis for family nursing and contributes to research, especially from the perspective of family welfare and its promotion. Family nursing research generates knowledge concerning families' and family members' wellbeing and experiences and expectations of nursing and health care.

METHODS

The examination of methodological problems while pursuing family research is based on two studies conducted in Finland.

FINDINGS

Quantitative methods add to the general knowledge of families. Qualitative methods are well suited to the study of family experiences. Family interviews performed for research purposes differ from interviews aiming at caring for families. They aim at obtaining knowledge of families on a general level so as to improve family nursing. Family research has to be looked at as a whole. It faces many challenges such as the definition of the family, gaining access, methods of data collection and data management.

CONCLUSIONS

A family is a complex system and research with families need flexible, sensitive and practical methods. Family research should also aim at developing new methods for data collection and analysis.

Risk factors of child maltreatment within the family: towards a knowledgeable base of family nursing

The purpose of this study was to compare family dynamics in child maltreating families (n=42) with that in ordinary families with children (n=77), and to ascertain risk factors of child maltreatment within the family. Child maltreatment was defined as physical, psychological or sexual abuse or neglect of a child by a parent. Data were collected using questionnaires (Family Dynamics Measure 2, FMD 2) (N=119) basing on Barnhill's conceptual framework of healthy family systems and analysed by forming sum variables and logistic regression. The study results indicate that family functioning in child maltreating families is lower on all dimensions of family dynamics (individuation, mutuality, flexibility, stability, communication and roles) than that in ordinary families with children. Furthermore, it seems that specific risk factors, detected with logistic regression analysis, are related to whether child maltreatment occurs in the family or not. These include the parent's low educational background, many children in the family, unemployment of a parent, low individuation of the family members, and poor stability and security within the family. The results of this study provide guidelines for detecting and preventing child maltreatment as well as for recognising its existence, although no generalizations can be made due to the small sample size and complexity of the phenomenon under study.

Family involvement in perioperative nursing of adult patients undergoing emergency surgery

The purpose of this study was to describe how adult patients undergoing emergency surgery experience family centredness in perioperative nursing practice. The central aim was to generate knowledge to be used while developing the practice, education and management of perioperative nursing. Data were collected using a questionnaire with emergency surgical patients in five regional hospitals in Southern Finland. The number of distributed questionnaires was 132. The response rate was 85% (n = 112). The results were mainly described as frequencies and percentages. The open-ended sections of the answers were analysed using qualitative content analysis. The findings from the open-ended questions were used for deepening and complementing the quantitative description of the results. In the preoperative phase, ascertaining the family situation and informing the family member chosen by the patient were not achieved systematically. Family situation was also rarely examined in the intraoperative and postoperative phases, although it is central to coping after surgery, especially in home care. The results support the view of earlier research about the importance of individuality of patients and their families during the perioperative care process and hence enhance the endeavour to develop nursing based on families' real needs.

Assessment of strategies in families tested by Finnish families

The aim of this paper was to describe testing a Finnish version of the assessment of strategies in families (ASF) instrument and its construct validity and reliability in Finnish families. The ASF instrument is based on Friedemann's framework of systemic organization and the version used in this study consists of 25 items, each containing three statements. The instrument was developed to estimate family functioning in reaching the four targets of the framework of systemic organization. It provides sub-scores for the targets, family stability (system maintenance and coherence), family growth (system change and individuation), control (system maintenance and system change) and spirituality (individuation and coherence). Data were collected from patients attending the outpatient clinics of pulmonary and rheumatic diseases (N=196). Questionnaires were given to patients capable of understanding the questions and they returned questionnaires by mail directly to researchers. Construct validity was tested with exploratory factor analysis. Factor analysis was done with 22 items. The four factor solution was best suited. Two items were eliminated because of low factor loadings and crossloading. The total of 20 items were left in the instrument. Crohnbach's alpha was used to measure internal consistency. It was computed for each target separately and the total tool. There were discrepancies in the assignment of process dimensions which were expected because of cultural perceptions. The total instrument had a reliability of 0.85. The result of the analyses was a pretested tool with subscales for stability, growth, control and spirituality that have acceptable reliability and concept validity. Less satisfactory was the small number of items representing individuation. Another weakness is the lack of statistical distinction between system maintenance and coherence. The instrument is also usable in these subscales, but it needs further development and retesting. Items need to be added to express individuation, possibly some others. The new items will be formulated freely, paying attention to culture. However, the tool appears good enough to be used as measurement in various research studies.

Family member as a hospital patient: sentiments and functioning of the family

The aim of this pilot study was to find out how families experience the hospitalization of one family member and to chart the participation of the family in the treatment of the hospitalized family member. A questionnaire was used to gather data for the study and the three open-ended questions in the questionnaire were interpreted using content analysis. The study population (n = 70) was the family members of patients in the neurological wards of Tampere University Hospital. The study demonstrated a variety of negative sentiments in the families, such as worry, fear, shock, anxiety and depression at the hospitalization of their family member. The families also expressed neutral and positive sentiments, such as approval, relief and faith in the help given. Nearly 80% of the families' statements dealt with emotional responses. Changes in the everyday life of the family caused by the hospitalization of a family member were also reported, with most changes affecting the immediate family. Hospital visits gave a rhythm to family life. There were changes in the sharing of housework and taking care of affairs, as well as in relationships within the family. Family members spoke of their loneliness, fear and longing. External changes in family life were present in 13% of statements. Helping the patient in hospital involved functions like participation in nursing care, taking the patient to the cafeteria and rehabilitation. Only 20% of statements dealt with emotional support for the patient. Future research could broaden the perspective to include the views of patients, nurses and doctors on the reality of family nursing.

Ethical problems in research on families who are abusing children

Child abuse within the family is a highly sensitive issue and therefore difficult to research. This article is based on our experiences of a child abuse research project in Finland. Special attention is given to ethical considerations during the initiation of the study, and in the sampling procedures, data collection and reporting. Most importantly, all those taking part in studies on sensitive issues must be guaranteed full confidentiality and anonymity. There are also other ethical considerations that go beyond the usual concerns in the research process.

The client-nurse relationship as experienced by public health nurses: toward better collaboration

This article presents the findings of a study concerned with the client-nurse relationship in public health nursing settings. The purpose was to look at the ways the client and public health nurse cooperate and to see what makes for efficient collaboration. A phenomenological-hermeneutic approach was adopted. The data consisted of essays written by the public health nurses and focused interviews, which were analyzed by phenomenological method. The outcome is an interpretive description of public health nurses' experiences of collaboration with their clients. Successful collaboration requires an active and committed involvement on both sides and a joint effort to help the client cope with his/her situation. This means there has to be not only a shared understanding of the ultimate goal of nursing, but also open and sincere confidence-building interaction for the creation of a sense of confidentiality and trustworthiness. The results suggest that the contents of the client-nurse relationship are extremely important to both sides of the dyad: both the client's well-being and the public health nurse's feeling of succeeding on the job will depend to a great extent on the kind of relationship they construct. Future research should also look at how clients experience their relationship with the public health nurse.

Dietary prevention of coronary heart disease in women: the Finnish mental hospital study

A controlled intervention trial, with the purpose of testing the hypothesis that the incidence of coronary heart disease (CHD) could be decreased by the use of a serum-cholesterol-lowering (SCL) diet, was carried out in two mental hospitals near Helsinki in 1959-71. The subjects were hospitalized middle-aged women. One of the hospitals received the SCL diet, ie a diet low in saturated fats and cholesterol and relatively high in poly-unsaturated fats, while the other served as the control with a normal hospital diet. Six years later the diets were reversed, and the trial was continued another six years. The use of the SCL diet was associated with markedly lowered serum cholesterol values. The incidence of CHD, as measured by the appearance of certain electrocardiographic patterns and by the occurrence of coronary deaths, was in both hospitals during the SCL-diet periods lower than during the normal-diet periods. The differences, however, failed to reach statistical significance. An examination of a number of potential confounding variables indicated that the changes in them were small and failed to account for the reduction in the incidence of CHD. Although the results of this trial do not permit firm conclusions, they support the idea that also among female populations the SCL diet exerts a preventive effect on CHD.

Dietary prevention of coronary heart disease: the Finnish Mental Hospital Study

A controlled intervention trial, with the purpose of testing the hypothesis that the incidence of coronary heart disease (CHD) could be decreased by the use of serum-cholesterol-lowering (SCL) diet, was carried out in 2 mental hospitals near Helsinki in 1959--71. The subjects were hospitalized middle-aged men. One of the hospitals received the SCL diet, i.e. a diet low in saturated fats and cholesterol and relatively high in polyunsaturated fats, while the other served as the control with a normal hospital diet. Six years later the diets were reversed, and the trial was continued another 6 years. The use of the SCL diet was associated with markedly lowered serum-cholesterol values. The incidence of CHD, as measured by the appearance of certain electrocardiographic patterns and by the occurrence of coronary deaths, was in both hospitals during the SCL-diet periods about half that during the normal-diet periods. An examination of a number of potential confounding variables indicated that the changes in them were small and failed to account for the considerable reduction in the incidence of CHD. It is concluded that the use of the serum-cholesterol-lowering diet exerted a substantial preventive effect on CHD.

Prevalence of cholelithiasis in men and women ingesting a serum-cholesterol-lowering diet

This study was carried out to ascertain whether, as has been suggested, the ingestion of a serum-cholesterol-lowering diet would be conducive to cholelithiasis. The prevalence of gallstones was studied in autopsied male and female patients of two mental hospitals in connection with a long-term controlled trial on prevention of coronary heart disease by means of a diet with a high polyunsaturated/saturated fatty acid ratio. The prevalence of gallstones was in men: 20/89 (equals 22.5%) on cholesterol-lowering diet and 11/44 (equals 25%) on normal diet; and in women: 151/262 (equals 42%) on cholesterol-lowering diet and 29/62 (equals 47%) on normal diet. It was concluded that in our trial the cholesterol-lowering diet was not lithogenic.
