Preschool children’s temperament and its associations with energy intake

Background and objectives

Child's temperament dimensions have been linked with different weight outcomes as well as dietary factors such as consumption of fruit and vegetables, sugar-rich foods and drinks and an overall dietary quality. Links between temperament dimensions and energy intake, however, remain under-examined. This study expands the literature by investigating associations between child's temperament dimensions and energy intake.

Methods

Altogether 505 Finnish children aged 3-6 years provided data for the analyses. The data is a part of the DAGIS (Increased Health and Wellbeing in Preschools) study conducted in 2015-2016. Child's energy intake was measured with 3-day food records. To be included, children had to 1) have food record for two preschool days and one weekend day and 2) to have consumed both lunch and an afternoon snack in the preschool on the two preschool days. The very short form of Children's Behavior Questionnaire was used to measure child's temperament dimensions. Concurrent associations between three temperament dimensions (surgency, negative affectivity, and effortful control) and energy intake were examined using linear regression models adjusted for child's age, sex, mother's highest education, and moderate-to-vigorous physical activity.

Results

Surgency, temperament dimension referring to characteristics such as impulsivity, high activity level and high approach, was positively associated with energy intake. Effortful control or negative affectivity were not associated with energy intake.

Conclusions

The findings imply that temperamental surgency may be one relevant determinant of energy intake among preschool children. The result is in line with previous studies linking child's surgency as well as its specific facets, such as impulsivity, with weight outcomes and food approach behaviors. Considering child's individual temperament dimensions when counselling families in eating issues could be beneficial.

Key messages

• Surgency, a temperament dimension referring to characteristics such as impulsivity, high activity level and high approach, was positively associated with energy intake.

• When promoting children’s balanced eating, tailored support for parents acknowledging child’s temperament could be beneficial.

Gaming is related to enhanced working memory performance and task-related cortical activity

Gaming experience has been suggested to lead to performance enhancements in a wide variety of working memory tasks. Previous studies have, however, mostly focused on adult expert gamers and have not included measurements of both behavioral performance and brain activity. In the current study, 167 adolescents and young adults (aged 13-24 years) with different amounts of gaming experience performed an n-back working memory task with vowels, with the sensory modality of the vowel stream switching between audition and vision at random intervals. We studied the relationship between self-reported daily gaming activity, working memory (n-back) task performance and related brain activity measured using functional magnetic resonance imaging (fMRI). The results revealed that the extent of daily gaming activity was related to enhancements in both performance accuracy and speed during the most demanding (2-back) level of the working memory task. This improved working memory performance was accompanied by enhanced recruitment of a fronto-parietal cortical network, especially the dorsolateral prefrontal cortex. In contrast, during the less demanding (1-back) level of the task, gaming was associated with decreased activity in the same cortical regions. Our results suggest that a greater degree of daily gaming experience is associated with better working memory functioning and task difficulty-dependent modulation in fronto-parietal brain activity already in adolescence and even when non-expert gamers are studied. The direction of causality within this association cannot be inferred with certainty due to the correlational nature of the current study.

Media multitasking is associated with distractibility and increased prefrontal activity in adolescents and young adults

The current generation of young people indulges in more media multitasking behavior (e.g., instant messaging while watching videos) in their everyday lives than older generations. Concerns have been raised about how this might affect their attentional functioning, as previous studies have indicated that extensive media multitasking in everyday life may be associated with decreased attentional control. In the current study, 149 adolescents and young adults (aged 13-24years) performed speech-listening and reading tasks that required maintaining attention in the presence of distractor stimuli in the other modality or dividing attention between two concurrent tasks. Brain activity during task performance was measured using functional magnetic resonance imaging (fMRI). We studied the relationship between self-reported daily media multitasking (MMT), task performance and brain activity during task performance. The results showed that in the presence of distractor stimuli, a higher MMT score was associated with worse performance and increased brain activity in right prefrontal regions. The level of performance during divided attention did not depend on MMT. This suggests that daily media multitasking is associated with behavioral distractibility and increased recruitment of brain areas involved in attentional and inhibitory control, and that media multitasking in everyday life does not translate to performance benefits in multitasking in laboratory settings.

Obstetric outcome after intervention for severe fear of childbirth in nulliparous women - randomised trial

OBJECTIVE

To compare the numbers of vaginal deliveries and delivery satisfaction among women with fear of childbirth randomised to either psychoeducation or conventional surveillance during pregnancy.

DESIGN

Randomised controlled trial.

SETTING

Maternity unit of Helsinki University Central Hospital.

POPULATION

Fear of childbirth was screened during early pregnancy by the Wijma Delivery Expectancy Questionnaire (W-DEQ-A). Of 4575 screened nulliparous women, 371 (8.1%) scored ≥ 100, showing severe fear of childbirth.

METHODS

Women with W-DEQ-A ≥ 100 were randomised to intervention (n = 131) (psychoeducative group therapy, six sessions during pregnancy and one after childbirth) or control (n = 240) (care by community nurses and referral if necessary) groups. Obstetric data were collected from patient records and delivery satisfaction was examined by questionnaire.

MAIN OUTCOME MEASURES

Delivery mode and satisfaction.

RESULTS

Women randomised to the intervention group more often had spontaneous vaginal delivery (SVD) than did controls (63.4% versus 47.5%, P = 0.005) and fewer caesarean sections (CSs) (22.9% versus 32.5%, P = 0.05). SVD was more frequent and CSs were less frequent among those who actually participated in intervention (n = 90) compared with controls who had been referred to consultation (n = 106) (SVD: 65.6% versus 47.2%, P = 0.014; CS: 23.3% versus 38.7%, P = 0.031). Women in intervention more often had a very positive delivery experience (36.1% versus 22.8%, P = 0.04, n = 219).

CONCLUSIONS

To decrease the number of CSs, appropriate treatment for fear of childbirth is important. This study shows positive effects of psychoeducative group therapy in nulliparous women with severe fear of childbirth in terms of fewer CSs and more satisfactory delivery experiences relative to control women with a similar severe fear of childbirth.

Goal reconstruction and depressive symptoms during the transition to motherhood: evidence from two cross-lagged longitudinal studies

Two cross-lagged longitudinal studies were carried out to investigate the extent to which the adjustment of personal goals to match the particular stage-specific demands of the transition to motherhood has consequences for women's depressive symptoms. In Study 1. 348 women filled out a revised version of Little's (1983) Personal Project Analysis and a revised version of Beck's Depression Inventory (A. T. Beck. C. H. Ward. M. Mendelsohn, L. Mock, & J. Erlaugh. 1961) 4 times: during early pregnancy, 1 month before childbirth, 3 months after childbirth. and 2 years after childbirth. In Study 2. 140 women who reported high levels of fear of childbirth filled out identical measures during early pregnancy, 1 month before childbirth, and 3 months after childbirth. The results showed that an increase in family-related goals during pregnancy and after the birth of the child predicted a decline in women's depressive symptoms. By contrast, an increase in self-focused goals predicted an increase in women's depressive symptoms.

A randomized controlled trial of intervention in fear of childbirth

OBJECTIVE

To compare intensive and conventional therapy for severe fear of childbirth.

METHODS

In Finland, 176 women who had fear of childbirth were randomly assigned at the 26th gestational week to have either intensive therapy (mean 3.8 +/- 1.0 sessions with obstetrician and one with midwife) or conventional therapy (mean 2.0 +/- 0.6 sessions), with follow-up 3 months postpartum. Pregnancy-related anxiety and concerns, satisfaction with childbirth, and puerperal depression were assessed with specific questionnaires. Power analysis, based on previous studies, showed that 74 women per group were necessary to show a 50% reduction in cesarean rates.

RESULTS

Birth-related concerns decreased in the intensive therapy group but increased in the conventional therapy group (linear interaction between the group and birth-concerns P =.022). Labor was shorter in the intensive therapy group (mean +/- standard deviation 6.8 +/- 3.8 hours) compared with the conventional group (8.5 +/- 4.8 hours, P =.039). After intervention, 62% of those originally requesting a cesarean (n = 117) chose to deliver vaginally, equally in both groups. Cesarean was more frequent for those who refused to fill in the questionnaires than for those who completed them (57% compared with 27%, P =.001). In the log-linear model, parous women who had conventional therapy and refused to fill in the questionnaires chose a cesarean more often than expected (standardized residual 2.54, P =.011). There were no differences between groups in satisfaction with childbirth or in puerperal depression.

CONCLUSION

Both kinds of therapy reduced unnecessary cesareans, more so in nulliparous and well-motivated women. With intensive therapy, pregnancy- and birth-related anxiety and concerns were reduced, and labors were shorter.

Psychosocial characteristics of women and their partners fearing vaginal childbirth

OBJECTIVES

To examine the personal characteristics and socio-economic background of women and their partners fearing vaginal childbirth.

DESIGN

Questionnaire survey by the 30th week of pregnancy.

SETTING

Sixteen outpatient maternity centres in the capital area of Finland.

PARTICIPANTS

Two hundred and seventy-eight women and their partners.

MAIN OUTCOME MEASURES

Personality traits, socio-economic factors, life and partnership satisfaction and pregnancy- and delivery-associated anxiety and fear.

RESULTS

The more anxiety, neuroticism, vulnerability, depression, low self-esteem, dissatisfaction with the partnership, and lack of social support the women reported, the more they showed pregnancy-related anxiety and fear of vaginal delivery. In multiple regression analyses psychological variables of the woman contributed most to the prediction of pregnancy-related anxiety (increase in R2 = 0.20, P < 0.001), the strongest predictor being general anxiety (beta = 0.28, P < 0.001). Lack of support contributed most to the prediction of severe fear of vaginal delivery (increase in chi2 = 13.66, P < 0.01), the strongest predictor being dissatisfaction with the partnership (Wald 8.61, P < 0.01). Life-dissatisfaction reported by the partner contributed to pregnancy-related anxiety and his dissatisfaction with the partnership contributed to the woman's fear of vaginal delivery.

CONCLUSIONS

The personalities of a pregnant woman and her partner, and their relationship, influences the woman's attitude to her pregnancy and her forthcoming delivery.

Psychosocial predictors of disappointment with delivery and puerperal depression. A longitudinal study

BACKGROUND

To examine the extent to which personality characteristics, depression, fear and anxiety about pregnancy and delivery, and socio-economic background, predict disappointment with delivery and the risk of puerperal depression.

METHODS

Two hundred and eleven women filled in questionnaires measuring personality traits, socio-economic factors, and marital satisfaction once before and once after the 30th week of pregnancy, and 2 3 months after delivery, when obstetric data about pregnancy and delivery was also collected.

RESULTS

The women who were disappointed with their delivery or suffered from puerperal depression had been more depressed already in early pregnancy. Regression analysis showed that the strongest predictors of disappointment with delivery were labor pain (increase in R2 = 0.14, p<0.001) and emergency Cesarean (increase in R2 = 0.18, p<0.001). Puerperal depression was predicted by depression (increase in R2 = 0.16, p<0.001), and by personal traits such as general anxiety, vulnerability and neuroticism (increase in R2 = 0.32, p<0.001), both before 30 weeks of pregnancy and prior to the delivery (for depression increase in R2 = 0.05, p<0.001, and for anxiety and vulnerability increase in R2 = 0.04, p<0.01). The strongest predictors were depression at both time points before delivery (beta = 0.51, p<0.001, and beta = 0.39, p<0.001). Pregnancy- and delivery-related anxiety prior to the delivery also predicted puerperal depression, but complications of the pregnancy and delivery did not.

CONCLUSIONS

Depression in early pregnancy predicts disappointment with the delivery and is a strong predictor of puerperal depression.

Women's and men's personal goals during the transition to parenthood

To investigate how women's and men's personal goals change during the transition to parenthood, the authors studied 348 women (152 primiparous and 196 multiparous) and 277 of their partners at 3 times: early in pregnancy, 1 month before the birth, and 3 months afterward. At each measurement, participants completed the Personal Project Analysis questionnaire (B. R. Little, 1983). The results showed that during pregnancy women became more interested in goals related to childbirth, the child's health, and motherhood and less interested in achievement-related goals. After the birth women were more interested in family- and health-related issues. These changes were more substantial among the primiparous than among the multiparous mothers. Although the men's personal goals changed during the transition to parenthood, these changes were less substantial than those found among the women.

Social strategies and loneliness

Although substantial research has been done on loneliness, in only a few studies has the extent of its association with the cognitive and attributional strategies people apply in social situations been investigated. Two studies were carried out among Finnish students to examine this association. In Study 1, 70 men and 202 women filled in the Cartoon-Attribution-Strategy Test (CAST) and Rosenberg's Self-Esteem Scale (RSE), then 1 year later, the revised UCLA Loneliness Scale. In Study 2, 25 men and 35 women filled in the CAST and the RSE, then 4 months later, the UCLA Loneliness Scale. In both studies, a pessimistic avoidance strategy was associated with subsequent feelings of loneliness, even after controls for the level of self-esteem. Both an optimistic planning strategy and a self-serving attributional bias were negatively associated with feelings of loneliness among men but not among women.

Personal goals of young social drop-outs

To examine the extent to which personal goals and their appraisals are associated with problems in socialization, 20 young 'social drop-outs' (15 men, 5 women) and 21 students from a vocational school (20 men, 1 woman) were interviewed about their personal goals, related views of internality, externality, and likelihood of accomplishing goals. Analysis indicated that young adults who showed problems in socialization mentioned less frequently personal goals related to future education and housing than did the control group. Second, social drop-outs held more external and less internal views and were less optimistic about accomplishing personal goals than was the control group.

Struggling with self: the personal projects of students seeking psychological counseling

Personal projects can be described as self-articulated goals and related sequences of actions. In order to investigate what kind of personal projects people with psychological problems have, and how they work on them, 28 counselling client students, 44 students of psychology, and 45 students of technology completed a Finnish version of Little's (1987) Personal Project Inventory. The results showed that the clients scored lower on project accomplishment than other groups. Their personal projects were frequently self-related, while those of the technology students were often task-related. The higher their sense of coherence, self-esteem, mental health and life satisfaction, the more subjects expected to accomplish their projects, the more frequently they described task-related projects, the less negative affect they reported, and the less frequently they described self-related projects. These results suggest that psychologically distressed individuals struggle with self-related projects and have problems in accomplishing their projects.

Age differences in adults' control beliefs related to life goals and concerns

Control beliefs play an important role in how people direct their own development during their life span. However, research into age differences in control beliefs has produced inconsistent results. In this study, 381 subjects (19 to 71 years old) completed a questionnaire in which they were asked to write down their goals and concerns. They were then asked to rate each on a 4-point bipolar rating scale measuring internality-externality. The results showed that subjects' control beliefs became more external with age. However, part of the increase in externality was found to be caused by increasing interest in domains that are generally considered uncontrollable. Subjects' beliefs about health-, self-, offspring-, and property-related goals became more external with age, unlike goals concerning future education, occupation, family, and travel.
